You will collaborate with designers, suppliers, and manufacturers to ensure functionality, quality, fit, and manufacturability. Strong knowledge of CAD, Adobe Illustrator, product development, garment construction, and Design for Manufacturing (DFM) is preferred. Candidates should demonstrate excellent attention to detail, technical problem-solving, and experience developing products from concept through production.

Hi,

I'm looking for a product designer to help me develop two concepts for a reusable siwak holder.

The first concept is inspired by a retractable highlighter pen. Instead of a marker tip, it would hold a small piece of siwak that extends and retracts with the click mechanism.

The second concept is inspired by a retractable lip brush. Instead of the brush, there would be a small piece of siwak that can be extended and retracted by twisting or using the existing mechanism.

The goal is to create a premium, practical, and reusable product that is comfortable to use and suitable for manufacturing.

Could you let me know if this is within your expertise? If so, I'd love to discuss the project and hear your thoughts on the best approach.

Thank you!

I run a small putter company and I'm looking for a long-term CAD partner, starting with
one well-defined project. Over the coming months I'll be re-creating four or five
classic milled putter designs from 3D scans, each with variations: different neck
styles, loft/lie tweaks, weight adjustments per build. I need one person who models the first head brilliantly and then becomes my go-to for modifications - small, fast,
recurring jobs on models you'll know inside out because you built them.

This first project: build a clean, manufacturable, fully parametric Autodesk Fusion model of a classic milled putter head (golf) from reference data I provide. This is a
real product that will be CNC-milled from bar stock, not a rendering exercise. I hold
the design rights to the original.

You will NOT be starting from nothing. You'll receive an unusually complete reference
package:

- High-resolution 3D scan of the physical head (mesh, millimetres)
- A complete dimensioned measurement recipe: every plane, angle, and blend radius
already extracted and fitted, with tolerances stated
- Reference photos of the physical putter
- Exact mass-properties targets (volume, weight, center of gravity) from the original
manufacturer's CAD data
- An existing rough model for comparison (do not reuse its geometry)

Deliverables

1. Native Fusion file (.f3d) with the **full parametric timeline intact** — a clean, ordered feature tree, not an imported dumb solid, not a converted mesh. This is a hard requirement: these models get modified repeatedly over their life, by you.
2. Named user parameters (naming conventions provided) for: cavity floor depth, loft, lie, bore diameter, hosel outside diameter.
3. The hosel/neck modeled as a separate body/component from the head, joined at a defined interface (details provided) - a second neck style will follow as a separate milestone, and swappable necks are core to the product line.
4. STEP export of the final solid.
5. Surface quality: tangent-continuous blends, no sliver faces, no stray edges, no knife edges except where the design calls for them. The part must look like what it is: a putter milled by a master, not a CAD reconstruction.

Acceptance criteria (objective - this is how the work is approved)

- Volume within 0.5% of the stated target; specified dimensions (bore, hosel OD, loft,
lie, key lengths) held exactly as specified
- Center of gravity within 0.25 mm of target on each axis
- Deviation against the scan: I will run an independent surface-deviation check on your
delivered model and share the report; systematic deviations over ~0.15 mm in defined
regions go back for revision
- Final visual approval against the physical putter is mine

Milestones (fixed price for this first project)

1. Head body block: primary surfaces from the dimension sheet, verified vs scan - 40%
2. Blends, refinements, surface quality pass, deviation report clean - 35%
3. Neck component + interface + parameters + STEP - 25%

The ongoing relationship (after this project)

If this first head goes well: recurring work at an agreed hourly or per-task rate -
additional heads (fixed price each), neck variants, and quick modification requests
("deepen the cavity 0.5 mm," "build this at 2° flat") where a 24–72 h turnaround
matters more than rock-bottom price. You'll work within my documentation and naming
standards (provided, lightweight) so every model in the line stays modifiable.

Required

- Strong Fusion 360 specifically (deliverable is a native parametric .f3d; SolidWorks-only need not apply)
- Demonstrated reverse-engineering from scan meshes of *machined* parts - show me examples
- Comfort holding dimensions to 0.05 mm against a spec sheet
- Responsive communication and interest in ongoing work, not just a one-off

To apply, briefly: (1) one example of a machined part you reverse-engineered from a scan, with a sentence on how you validated it; (2) your approach to keeping blends tangent where three surfaces meet; (3) confirmation you'll deliver the parametric
timeline, not an export; (4) your typical turnaround for a small modification to a
model you previously built, and how you price those.

Work-for-hire; all rights assigned; reference materials are confidential and not for
portfolio use without written permission.

Packaging Engineer / Product Design Engineer – Adaptive Dispensing Closure (Patent Opportunity)

Project Overview

I’m looking for an experienced packaging or mechanical engineer to help invent a new dispensing closure for children’s personal care products.

The goal is not to copy an existing product, but to develop a novel dispensing mechanism that improves independence while preventing waste and over-dispensing.

This is an early-stage invention with the potential to become patentable and evolve into a long-term collaboration.

The Problem

Current squeeze bottles allow children to accidentally dispense far too much product, creating waste and frustration.

I want to create an adaptive dispensing closure that:

* Dispenses a consistent amount with each squeeze
* Is easy enough for young children to operate with one hand
* Minimizes dripping
* Uses no traditional flip cap
* Reduces accidental over-dispensing
* Encourages independent use
* Works with lotions, body wash, shampoo, and sunscreen

What I’m Looking For

Someone with experience in:

* Consumer packaging
* Dispensing systems
* Plastic closure design
* Injection-molded products
* Silicone valves
* Fluid mechanics
* Mechanical product development
* CAD (SolidWorks, Creo, Fusion 360, or similar)

Experience with personal care, medical, or food dispensing products is highly preferred.

Project Deliverables

Phase 1 (only hiring for Phase 1 at this time)

* Review product requirements
* Brainstorm multiple engineering concepts
* Recommend the most promising approach
* Identify technical challenges

Phase 2

* Develop CAD concepts
* Design internal dispensing mechanism
* Recommend materials and manufacturing methods
* Prepare prototype-ready files

Future phases may include prototype testing and design refinement.

Important

The objective is to create an original engineering solution.

Applicants should be comfortable designing around existing products while avoiding infringement of existing intellectual property.

Experience supporting patent development is a plus.

To Apply

Please include:

* Examples of dispensing systems or packaging you’ve designed
* Relevant patents or products you’ve worked on (if publicly shareable)
* Your CAD software
* Years of experience
* Why this project interests you

Please begin your proposal with the word “Sapito” so I know you’ve read the full description.

Budget

Open to fixed-price or hourly proposals based on experience.

Potential for long-term work as the project advances.

We need an experienced SolidWorks modeller to urgently complete and correct an existing 3D as-built model of a concrete structure.

A substantial amount of modelling has already been completed. We can provide:

Existing STL, OBJ and DWG files
Partial Revit model for reference
Point-cloud/scan reference
Comparison screenshots showing areas requiring correction
Access to an online scan/model viewer

The structure includes non-standard tapered columns, beams, panels and connection geometry. Many components vary and cannot simply be copied as repeated standard parts.

Required work
Review the existing files and identify what can be reused
Correct inaccurate or incomplete geometry
Complete the remaining structural elements
Model directly against the supplied scan data
Produce clean, editable SolidWorks geometry
Maintain the existing coordinate position and scale
Provide progress screenshots comparing the CAD model against the scan
Produce basic elevation drawings referenced to the supplied datum if required

We're looking for a CAD designer who is highly experienced with Autodesk Fusion to create parametric part models for CNC manufacturing.

This is not a general CAD role. We need someone who is comfortable building clean, robust parametric models that can be resized simply by changing spreadsheet values.

Most projects involve straightforward parts, but the models need to be built correctly so they remain reliable when dimensions change.

What we need
One parametric Fusion part per item, saved as a .F3D file.
Software: Autodesk Fusion
Toolpaths/CAM: Not required (we generate our own CAM). If you also have CAM experience, please mention it in your proposal.
Deliverables

For every part, please provide:

The .F3D file containing the parametric features.
A one-line name for the part.
To apply

Please answer these three questions:

1. Have you built Fusion models driven by a spreadsheet of parameters using aliases and expressions?

Please describe a real example.

2. When creating parametric models, how do you ensure they continue working when dimensions change significantly?

Please include
Examples of Fusion models you've created (Fusion specifically, not SolidWorks or Rhino).
Confirmation that you're comfortable creating parametric models.
Your hourly rate and availability.

We're a small consumer products startup working on an ergonomic handheld product (kitchen/outdoor category). We already have a working 3D-printed prototype but no clean CAD source - the original was done quickly in a mesh tool and is not useful for iteration or manufacturing.

We need an experienced mechanical designer to reverse-engineer the physical sample into clean parametric CAD, do a light industrial design pass, and give us DFM notes so we're ready for injection-molded tooling later.

Project scope:

1. Reverse engineering - we'll send you calipered dimensions, photos from multiple angles, and a short video walkthrough of the existing 3D-printed prototype. Rebuild it as clean parametric CAD in SolidWorks or Fusion 360.

2. Product & Industrial Design pass - light refinement of ergonomics and form. Nothing radical, just cleaning up transitions, fillets, grip zones so it feels premium.

3. Design for Manufacturing notes - flag anything that would cause trouble for injection molding later: wall thickness, draft angles, parting line suggestions, undercuts. Not full mold design, just a written DFM review (1-2 pages) so we know what to redesign before we commission tooling.

4. 3D printing files - export STL ready for our next validation print (FDM), with a short note on recommended print orientation and supports.

Deliverables:

- Parametric CAD source files (SolidWorks or Fusion 360)

- STEP export

- STL export for 3D printing

- DFM review notes (short PDF or doc)


What we're looking for:

- Strong 3D CAD (SolidWorks or Fusion 360) — clean parametric feature tree

- Reverse engineering from photos, dimensions, and reference prototypes

- Product & Industrial Design sensibility

- Design for Manufacturing experience with injection-molded plastic parts

- 3D printing prototyping experience

In your proposal, please include:

- 1-2 similar past projects (consumer product, ergonomic — links if visible)

- Your CAD software preference (SolidWorks vs Fusion 360)

- Estimated timeline

I need a CAD designer to create patent-ready 3D models for a consumer product with organic curves and a hinge mechanism. Must have experience with consumer product CAD, organic surface modeling, and be comfortable signing an NDA.

Looking for an experienced CAD designer (Rhino, Fusion 360, SolidWorks, or MatrixGold) to create a precision 3D .STL model file for custom luxury accessory hardware.
Project Highlights:
Creation of a custom clip mechanism with exact inner specs (15.5mm×3.0mm).
Incorporates basic gemstone settings/seats on the hardware body.
Deliverable: Clean .STL file ready for high-resolution SLA resin 3D printing.
Requirement: Designer must sign a simple 1-page Singapore NDA before receiving the exact design brief/sketches.

CAD Design of Aaterproof Aluminium Enclosure of an Automotive ECU

Hello Dhruvi,

I have a small CAD modification project.

I will provide:

A STEP assembly consisting of only 2 parts (main body and rear cover).
A simple AutoCAD drawing showing the new concept and the two critical dimensions.

The current rear cover slides into a groove, but I would like it redesigned as a hinged cover. The main body must therefore be modified to accommodate the new hinge.

The new cover should:

Open and close on a hinge as shown in the attached drawing.
Have a light snap-fit when closed.
Be easy to open using a fingernail or a thin tool.

For this initial project, only the external housing and the rear cover need to be modified. I expect to have more CAD modification projects in the future, and possibly also SLS 3D printing work.

Deliverables:

Modified STEP assembly.
Individual STEP files for the two modified parts (if possible).

Please let me know:

If anything is unclear.
Your estimated fixed price.
Your estimated delivery time.

Thank you,
Jan Roar

We have a spreader beam, we need to insert the beam drawing in to customer drawing and define the COG, position the beam and share the lifting drawing.

We're building BlueCat, an AI literacy platform that teaches children aged 7–12 to think critically about AI. Part of the product is a small desktop
robot that talks with children through voice.

The electronics work today. We need someone to design the body: a 3D-printable character shell that our components fit inside, and that a
child wants to pick up.

BlueCat is an established brand character a friendly, rounded blue cat. We'll share the full character guidelines, colour system and existing
illustrations with the selected freelancer.

This is not a "design a robot from scratch" job. It's translating an existing 2D character into a printable 3D object that houses real hardware.


WHAT WE ALREADY HAVE

- Working electronics: ESP32-S3 dev board, I2S microphone, class-D audio amplifier, speaker, volume potentiometer, push-to-talk button
- Exact component dimensions and photographs of the assembly
- Full BlueCat character brand guidelines — colours, proportions,
personality, and existing illustrations from our books and app
- Access to a 3D printer for iteration

WHAT WE NEED YOU TO DESIGN

A two-or-more-part printable shell in the shape of the BlueCat character,

that:

1. Houses the electronics securely, screw bosses or heat-set insert bosses, board standoffs, no rattling, no strain on solder joints.

2. Has a proper acoustic path for the microphone (see below).

3. Has a proper speaker chamber — not a hollow box the speaker rattles in.

4. Gives access to the USB-C ports, push-to-talk button, volume knob and status LED.

5. Opens for service without breaking, and closes without visible gaps.

6. Prints cleanly with minimal supports on a consumer FDM printer, and is also suitable for resin printing for a higher-finish demo unit.

7. Is safe for a child to handle, rounded edges, no pinch points, no small detachable parts, no sharp internal edges reachable through openings.

THE TWO REQUIREMENTS WE CARE ABOUT MOST

Microphone acoustics. The robot's entire purpose is understanding children's speech. A badly ported microphone kills the product. We need a
designed acoustic path, correctly sized port, a short sealed channel from the port to the MEMS mic inlet, a gasket, and isolation from speaker
vibration through the chassis. If you've done this before, tell us about it in your proposal.

Speaker enclosure. Same reasoning in reverse. We need a sealed or deliberately ported chamber sized to the driver, with a gasket and a grille
pattern that's printable without supports, so the robot sounds warm rather than tinny.

If your proposal doesn't mention either of these, we'll assume you haven't done functional audio enclosures.

DELIVERABLES

- Editable source files , native (.f3d / .sldprt) AND .STEP

- Print-ready meshes, correctly oriented — .STL and .3MF

- Assembly drawing / exploded view (PDF)

- Bill of fasteners — screws, heat-set inserts, gaskets, with part numbers

- Print settings recommendation — material, layer height, infill, supports, orientation

- At least one validated test print, with photos of the real assembly and our electronics fitted and we will also test print on our side.

- A short screen recording walking through the source files, so we can modify them later

The validated test print is not optional. We're not accepting a model that has never been printed and fitted.

REQUIRED SKILLS

- Parametric CAD for enclosure design — Fusion 360, SolidWorks or Onshape

- Demonstrated experience designing enclosures around real electronics, not decorative prints

- Understanding of FDM and SLA tolerances, shrinkage and fit clearances

- Design for manufacture, draft angles, wall thickness, support minimisation, print orientation

- Screw bosses, heat-set inserts, snap fits, living hinges

- Portfolio showing at least one product that opens, closes and holds a PCB

STRONGLY PREFERRED

- Character or toy design experience — organic, appealing forms rather than boxy utility cases

- Acoustic design — speaker chambers, microphone ports, gaskets

- Blender / ZBrush / Nomad for organic sculpting combined with parametric CAD for mechanical features

- Consumer product or children's toy background

- Awareness of toy safety standards (EN 71, ASTM F963). We're not certifying at this stage, but we don't want to design ourselves into a corner.

NOT REQUIRED

Rendering and animation. We want a working object, not a marketing image.

MILESTONES

1. Concept sketches / blockout with 2–3 directions, character proportions
agreed

2. CAD draft — full internal layout, all components placed

3. Test print and fit real parts, our electronics inside, photos

4. Final files and documentation

SKILLS:

Convert Mat Artwork to STEP Files (Dense Dot Texture, Two Faces)

I need a CAD specialist or industrial designer to convert two Adobe Illustrator files for a moulded mat into watertight STEP solids.

The files are the front and back faces of the mat, a flat rectangle measuring 500 by 320 millimetres. Each face carries a dense field of small round dots, roughly 1.37 millimetres in diameter and close to 57,000 per face, on a regular rotated lattice. The dots should be generated from the coordinate data in the files rather than placed by hand.

Deliver two STEP files, one per face, watertight and suitable for tooling, with dot diameter, spacing, and lattice orientation faithful to the source, and the branding reproduced as marked.

Tell me how you would generate the dots and in what software, and give me a fixed price and a realistic turnaround. I will send the artwork once we have agreed terms.

Deliverables:

Watertight STEP file for the front face of the mat, with accurately generated dot field and branding
Watertight STEP file for the back face of the mat, with accurately generated dot field and branding

Candidate Info
You build geometry from coordinate data using a scripted or parametric CAD workflow, rather than placing features by hand.
You can extract the dot positions and sizes from vector artwork and feed them into your model cleanly.
You produce watertight, manifold solids, with booleans and tolerances handled reliably across tens of thousands of features.
You can export a clean STEP file suitable for tooling and manage a model of this density without it becoming unworkable.

We are a German engineering service provider. We handle the client relationship, quality review and final release. You handle the design and drafting work.

We are looking for a long-term partner — freelancer or agency — not a one-off job.

What we provide

• Clear technical briefs, specifications and reference drawings
• Our drawing templates, title blocks and naming conventions
• Defined scope per project: components, assemblies, deliverables
• Steady project flow once quality is proven

What you deliver

• 3D modelling of components and assemblies
• 2D drawing derivation with full dimensioning
• Parts lists / BOM
• Variant design based on existing models
• Native files plus STEP export
• Reliable turnaround on agreed deadlines

Software

• SolidWorks and/or Autodesk Inventor (state which you use)
• Own commercial licence required — proof needed. Student, trial or unlicensed versions are not acceptable.
• State the exact version you work with. Our clients often run older releases and must be able to open the files.

Critical requirement — please read carefully

Our clients are German machine builders. Drawings must comply with German and European standards, not ASME:

• Dimensioning and tolerancing per DIN ISO 286 and ISO 2768
• Geometric tolerancing per ISO 1101
• Welding symbols per ISO 2553
• Surface finish per ISO 1302
• Metric only

If you have never worked to these standards, say so openly. We would rather train the right partner than correct drawings on every delivery.


Experience with German-speaking clients

Have you worked for German, Austrian or Swiss clients before? If yes, name the type of company (machine builder, plant engineering, tooling, automotive supplier) and for how long. This is not a hard requirement — it tells us how much guidance to expect in the first projects.

Please send: one full manufacturing drawing as PDF (zoomable), one assembly with parts list, one native file, and the original brief for one of them.

Data handling

• Client data must be stored securely and deleted after project completion on request
• No third-party subcontracting without our prior written approval
• Please state where data would be stored and who would have access

Rights and rework

• All rights to the delivered files transfer to us. Work may not be used as your own reference or portfolio material without written permission.
• Rework due to deviation from our standards or briefs is corrected at no additional cost.

Please include in your proposal

• Team size, current availability and how many hours per month you can reliably deliver
• How you handle absence, holidays or peak load
• Your proposed rate — hourly, or per project if you prefer
• Typical turnaround for a mid-size assembly (roughly 200 hours of work)
• Two reference drawings you produced, ideally to DIN or ISO standards
• One before/after example: a project where you received an incomplete or unclear brief. Show the input you were given and the final drawing. We want to see how you handle gaps, not only polished work.
• Experience with German-speaking clients: yes or no, and if yes, which industries
• Software and exact versions you work with
• Where client data would be stored

Do not send generic proposals. We will only review submissions that address the points above.

Summary

I am seeking an experienced mechanical engineer with expertise in CAD and mechanical product design for the first phase of a confidential consumer product.

The goal of this phase is to evaluate the concept, identify any major mechanical challenges, and develop an initial 3D CAD assembly of the product. This phase is intended to determine technical feasibility before moving into prototype development.

The ideal candidate has experience designing mechanical consumer products, mechanisms with moving parts, and creating CAD models suitable for 3D printing and future prototyping.

This project is confidential. An executed Non-Disclosure Agreement (NDA) will be required before any details of the invention are disclosed.

Please include the following in your proposal:

* A brief summary of your experience designing mechanical consumer products.
* Examples of relevant CAD or prototype work (if not confidential).
* The CAD software you primarily use.
* Your experience designing mechanisms with moving parts such as levers, sliding components, springs, cams, or linkages.
* Whether you can provide native CAD files and STEP files upon completion.

This is the first phase of a larger project. If the initial design is successful, additional milestones for prototype development, design refinement, testing, and manufacturing preparation may follow.

I need a mechanical engineer to design a segmented link track for a small drive system. The track should be metal chain-style, not rubber, and require precision and technical expertise. The project involves creating a detailed design and simulation to ensure functionality and efficiency.

I have a machine with several parts. I have a step files for the whole machine, but I need to do the drawing for a few parts. These drawings must be pdf with all dimensions.
In particular I would like to start with one of the parts, which is named reflector.
If you are available and has interest, let's set a meeting where a can share the files and explain what is the tasks in details.

Thank you,
Regards,
Elcio

• ​Equipment Limitations: The design of all units and components must be strictly adapted for laser, waterjet, or plasma cutting, as well as CNC bending.
• ​Project Format: The deliverables must be presented as a detailed 3D model (assembly) that can be freely rotated to examine the internal structure, individual parts, and key bolted/riveted connection joints.
• ​Frame and Cladding Material: AISI 304 sheet stainless steel (matte finish), sheet thickness — 1 mm.
• ​Structural Design: A system of profiles/angles with mandatory metal hemming/flanging on all elements where a user could get injured during box operation (all edges must be smooth, free of burrs and sharp edges, executed via safe bending/hemming on a press brake).
• ​Wall Insulation (Sandwich): Basalt wool (mineral insulation) with a thickness of 30 mm.
• ​Wall Cladding: The basalt wool is enclosed on both sides (inside and outside the box) with smooth stainless steel sheets.
• ​Hardware and Fasteners: Assembly is carried out strictly using bolts, nuts, washers, as well as threaded and blind rivets made of stainless steel (A2/A4) to completely eliminate corrosion.
• ​Hygiene: The internal working area of the box must be as smooth as possible, with a minimal number of protruding fasteners and crevices to facilitate easy periodic cleaning and surface disinfection.
• ​Legs: 50 mm in height, rigidly integrated into the lower structural contour of the frame (designed via sheet metal bending). The lower (bearing) plane of the legs must include mounting holes for reliable bolted fixation of the thermobox to a pallet or installation platform.
​2. DOOR AND LOCKING MECHANISM DESIGN
• ​Airtightness: Mandatory presence of a high-quality rubber seal around the entire perimeter of the door rabbet and a pressure (clamping) bar to ensure 100% sealing and elimination of gaps.
• ​Hinges: Custom-made using laser cutting and CNC bending. The doors and frame must have precise seating locations (using a "mortise and tenon" / matrix-punch principle) to prevent sagging and backlash. Bolts serve exclusively for clamping purposes.
• ​Locking: Doors are secured by simple and reliable mechanical latches (pin latch based on a "pin-in-hole" principle), which are also custom-made via CNC laser cutting and bending.
• ​Door Configuration (for PRODUCT No. 1): A single-piece door covering the full width and height of the opening. An opening utility hatch is integrated into the lower part of the door. The maximum possible remaining area of the door leaf is occupied by a viewing window.
• ​Viewing Window (Product No. 1): Consists of two 5 mm glass panes with an air gap between them. The glass must be removable. Clamping frames (made via laser cutting from sheet metal) must provide secure and airtight fixation of the removable glass panes using bolts/rivets.
​3. VENTILATION SYSTEM
• ​Protective Mesh Parameters: A stainless steel protective mesh (wire thickness — 0.5 mm, mesh size — 0.8 mm) is installed on all ventilation openings. Mounting is done via removable stainless steel clamping frames secured by screws/bolts to tightly fix the edges (without drilling the mesh itself).
• ​Upper Forced Exhaust (for a 120 mm cooling fan, identical for both products):
◦ ​A square cutout in the roof (top panel) measuring 200x200 mm (area: 400 cm²).
◦ ​Fan installation via a transitional metal diffuser/flange adapter (assembled from sheet metal on a CNC press brake + bolts/rivets; fan mounting holes — 105x105 mm, 4 holes with a diameter of 4.5 mm for M4 bolts, central hole 113 mm).
◦ ​An adjustable mechanical damper (slide gate) located under the fan (above the mesh).
• ​Lower Air Intake (on side walls, 100 mm from the floor, with adjustable slide gates):
◦ ​For PRODUCT No. 1 (Vertical Box): Two openings (left and right) with a cross-sectional area of 250 cm² each (size: 25x10 cm).
◦ ​For PRODUCT No. 2 (Horizontal Box): Two openings (left and right) with a cross-sectional area of 250 cm² each (size: 25x10 cm).
​4. PRODUCT SPECIFICATIONS
• ​PRODUCT No. 1 (Vertical Box):
◦ ​External overall dimensions: Width — 600 mm, Depth — 600 mm, Height — 1200 mm.
◦ ​Door: Single-piece, with an integrated bottom opening utility hatch and a large viewing window (two removable 5 mm glass panes with an air gap).
◦ ​Ventilation: Upper exhaust 400 cm² (for a 120 mm fan) + 2 lower intakes of 250 cm² each (25x10 cm) with adjustable slide gates.
◦ ​Internal equipment: Brackets/mounts for lighting lamps, sealed cable penetrations, mounts for IR heating film (on the wall), stand, bars/rails for hanging an internal mesh insect cage (all made from sheet metal).
◦ ​External equipment: A mount (bracket) on the side for installing a control panel.
• ​PRODUCT No. 2 (Horizontal Box):
◦ ​External overall dimensions: Width — 600 mm, Height — 600 mm, Depth — 400 mm.
◦ ​Door: Single-section solid (without glazing), front-opening.
◦ ​Ventilation: Upper exhaust 400 cm² (for a 120 mm fan) + 2 lower intakes of 250 cm² each (25x10 cm) with adjustable slide gates.
◦ ​Internal equipment: Mounts for lighting lamps, cable penetrations, mounts for IR heating film (on the wall), integrated stainless steel runners for installing shelves, shelves (bent sheet metal profile).
◦ ​External equipment: A mount (bracket) on the side for installing a control panel.
​5. REQUIRED DELIVERABLES:
1. ​3D Models: In STEP / SolidWorks formats for both products, detailing all profiles, bending nodes, custom hinges/latches, and fastening elements (bolts/rivets).
2. ​Drawings (Design Documentation): A set of detailed drawings for parts and assemblies, indicating all dimensions, tolerances, and part connection diagrams.
3. ​Flat Patterns (Unfolds): DXF files, strictly prepared for sheet laser cutting, accounting for bend allowances (K-factor) for stainless steel on a CNC press brake.
4. ​Bill of Materials (BOM): A consolidated table of materials and fasteners used (hardware and rivets: dimensions, standards, and exact quantities).

Summary
We are seeking a skilled freelancer to create CAD objects using OnShape. The ideal candidate will have experience in 3D design and modeling, with a strong understanding of CAD software. Responsibilities include designing and modeling CAD objects, ensuring accuracy and precision, and collaborating with our team to meet project requirements.

I'm attaching two documents:

1. Onshape CAD Annotation Guidelines: the exact workflow and submission spec for this work. A few requirements worth flagging up front, since they go beyond a typical CAD recreation task:
- Modeling must be done natively in Onshape, using only the project-assigned account. No imported/linked geometry, no third-party or Onshape Standard Content, no mesh-only models.
- Every session needs synchronized screen and input recording via a specific tool pairing (AgentNet + OBS), following an exact setup (fixed resolution/zoom, project-assigned accounts only, no extra overlays).
- Submission has two required parts: the finalized Onshape document (named version V99_FINAL) plus the complete raw AgentNet session folders, not just a video.

2. CAD Assets: reference GrabCAD models across five categories (robotic arm, V6 engine, V8 engine, jet engine, motorbike) representing the complexity we're targeting.

You final CAD object video has to match the defined CAD asset. (History should be on OnShape)

We need a drawing made for a basic CNC Lathe part. The designer will be provided with a STEP file or a SLDPRT file depending on their preference. The designer should be familiar with proper GD&T as the drawing will be sent to suppliers to manufacture samples.

The part is a pen composed of 3 parts. A screenshot of the cross-section is attached. The pen uses a triangular thread profile that the designer should be able to properly indicate in a drawing. The part will be anodized, and the designer should ensure a loose fit of the threads even after anodization. We will not be masking the threads for anodization.

I am developing a premium indoor hydroponic growing cabinet for home use.

The engineering concept, dimensions and layout are already decided. I am looking for a Mechanical CAD Designer to convert my sketches, notes and ideas into a complete SolidWorks model and manufacturing drawings.

This is not a product design project. I will provide the engineering direction and make all design decisions.

Scope of Work

The work includes:

Create complete 3D SolidWorks assembly
Create weldment frame
Design sheet metal panels
Create grow trays and reservoir
Add purchased components (drawer slides, hinges, fans, pumps, etc.)
Check assembly for interferences
Generate manufacturing drawings
Create DXF files for laser cutting (later stage)
Update CAD based on review comments
Skills Required
SolidWorks (Essential)
Weldments
Sheet Metal
Mechanical Assembly
Manufacturing Drawings

Experience with hydroponics is not required.

This is not a creative design job.

I am looking for someone who can accurately convert instructions into CAD.

If something is unclear, I expect you to ask questions rather than make design decisions.
