Freelance Solidwork designer jobs

We're developing a premium body pillow designed specifically for side sleepers and are looking for an experienced CAD designer with a strong background in organic surface modeling. This project goes far beyond creating a model from dimensions—we need someone who understands ergonomics, human interaction, and how to transform those principles into a manufacturable product.

The pillow must feel completely intuitive. Regardless of how it's picked up or positioned, the user should experience it naturally without needing to determine a top, bottom, left, or right side. The final design should appear seamless and intentional, with smooth, continuous surfaces that feel like the only possible solution.

This opportunity is not suited for designers whose experience is primarily focused on:

Mechanical components or brackets
Plastic enclosures or injection-molded parts
Sheet metal or structural CAD

We're looking for professionals with experience designing:

Furniture, bedding, or soft goods
Ergonomic consumer products
Foam-based products
Medical or wearable products featuring refined organic surfaces

Phase 2 – Production CAD Package

Final watertight solid model.
STEP, IGES, and native CAD files.
Orthographic views and cross-section drawings.
Surface continuity validation (G2/G3 preferred).
Manufacturing notes suitable for the supplier.

A reference render will be provided to communicate the design intent. It should serve only as inspiration for the design direction and should not be copied directly.

Required Skills
Advanced proficiency in SolidWorks, Rhino, Alias, Fusion 360, or similar CAD software.
Strong expertise in freeform and organic surface modeling.
Ability to produce clean, watertight geometry.
Excellent English communication skills.
Preferred Qualifications
Experience designing foam, furniture, bedding, or ergonomic consumer products.
Understanding of foam manufacturing and single-pour mold considerations.
Previous collaboration with overseas manufacturers.

Project Title: Bending Jig and Ejector Mechanism (Pneumatic)
Project Overview:
I am looking for a mechanical designer to create a simple, custom fabrication fixture/jig. The machine needs to position a small flat metal part, bend a designated section, and then automatically eject the finished piece. I intend to fabricate the machine myself from the final blueprints. I have attached a rough sketch of what I had in mind. Some sort of part holder that the flat pieces can stack in. A way to push it over into the jig, form and eject. Ideally this machine can be turned on and it will run parts. Not sure how to add any safeties incase of a jam or issue.

Sketch is a concept and I am open to any design changes. Currently part just ejects out into a bucket/container.
Material & Part Specifications:
Stock Material: 14-gauge (~0.075" thick) carbon steel.
Blank Size: Approx 2” x 4” oval
Bending Operation: The machine needs to form a smooth 0.72" radius bend on a 1/2" wide strip/arm located on the part.
Required Machine Sequence:
Move: Move the 4" x 2" flat blank into the bending jig nest.
Bend: Form the .72" radius bend on the 1/2" wide strip section.
Eject: Automatically eject the finished part out of the jig.
Component Constraints (Design around existing hardware):
To minimize my material costs, the design must be built around a specific pneumatic cylinder I already own.
Cylinder Specs: 1-1/2" Bore, 3" Stroke pneumatic cylinder - mid‑trunnion mount
Operating Pressure: Standard shop air (~90 PSI).
Please utilize standard, off-the-shelf catalog mounting hardware (e.g., McMaster-Carr or similar) for the cylinder brackets and pivots.
Wear parts, like the fixture, please design with 3/8" Material. I have 3/8" AR500 plate I will use.
I have a CNC Laser and Fab shop, so custom metal design is fine, as I will fabricate in house.
Required Deliverables:
Complete 3D CAD Assembly files (STEP or IGS format).
2D manufacturing blueprints with dimensions for shop fabrication.
Flat-pattern DXF files for laser cutting the raw plate components.
A basic Bill of Materials (BOM) listing any off-the-shelf pins, springs, or fasteners used.

Hello, I have an existing fishing lure that I'd like to prepare for manufacturing. The original files I have are an OBJ and STL, and I also have a STEP file that was created from those models. My goal is to rebuild the design into a fully editable, manufacturing ready SolidWorks model suitable for injection molding.

I'd like to:
* Convert the STEP file into a fully editable SolidWorks model.
* Preserve the appearance and dimensions of the lure.
* The final deliverables should be suitable for injection mold manufacturing and include:
* Native SolidWorks
* Parasolid (.x_t)
* STEP (.step)

A few questions:
1. Approximately how many hours do you estimate this would take?
2. Based on your experience, is rebuilding the model from the files I have doable?

Thank you! I look forward to hearing your thoughts.

Best,
Brian

I need someone to design an STL or 3MF file for my Bambu P1S printer (FDM 3D printer) that uses PETG filament.

Mechanical Engineering Partner – Surfboard Rack Product Development
Project Overview

This project involves refining an innovative roof-mounted surfboard rack from a proven proof-of-concept into a functional prototype ready for testing and manufacturing validation. I am seeking an experienced Mechanical Engineering Partner to develop CAD models, design 3D-printed prototype components, evaluate manufacturing methods, and estimate production costs for low-volume manufacturing (100–1,000 units). This is an opportunity to become a long-term engineering partner and help bring a new consumer product to market.

I am looking for a top-tier Mechanical Engineer / SolidWorks drafting technician to execute a ground-up internal mechanical optimization, formal engineering drawing generation, and Bill of Materials (BOM) compilation for a premium consumer hardware device. This product is manufactured 100% out of Multi-Jet Fusion (MJF) Plastic (Nylon 12) with no metal components. Because of this, structural wall integrity and precise tolerancing are paramount.

The foundational engineering, external scale, and core mechanism are already physically proven through working prototypes. Your job is to correct specific internal mechanical defects left by a previous freelancer and deliver a complete, production-ready documentation package without altering the external aesthetic or scale of the device.

What you will be doing:
Optimize the Drive Enclosure (Top Cap) Torque Interface: Refine the internal, hidden drop-and-slide keyway inside the Drive Enclosure to cleanly capture a robust 8.0mm nominal square drive shank. The previous freelancer restricted the entry opening to 6.1mm, causing a massive structural shear bottleneck. You must eliminate this bottleneck, open the entry track to a precise 8.3mm to 8.4mm wide sliding clearance, and eliminate the legacy set-screw hole entirely. The interface must be a pure, tight geometric lock with a completely solid outer enclosure profile.

Open the Central Sleeve Clearance Bore: Modify the internal clearance bore of the Main Housing Sleeve to easily pass the 11.3mm diagonal corners of the 8.0mm square drive shank. Do not weaken or neck down the drive screw to fit the sleeve.

Redesign Plunger (Piston) Rotational Coupling: The 13.8mm Plunger Face currently snaps onto the bottom of the Drive Screw under zero load, but torques right off during actual material compression due to raw-on-raw MJF surface friction. Redesign this connection into a heavy-duty, low-friction rotational coupling (e.g., a captive retaining pin or interlocking collar) that completely decouples the screw's rotation from the linear travel of the Plunger Face so it never pops off under load.

Verify Linear Stroke & System Function: Ensure the system flawlessly accommodates the full stroke of the 45mm lead screw within a fixed external housing length of exactly 71.5mm. The Plunger must retract fully for loading and extend deep enough to compress material into a dense, perfect 14.0mm diameter puck without bottoming out prematurely.

Consolidate & Clean Components:
The separate, old threaded "fix insert" part is completely redundant and must be deleted. Integrate its internal guiding flange geometry directly into the top profile of the Main Housing Sleeve.

Remove the protruding center artifact/nub from the Bayonet Closure (Bottom Cap) entirely. The bottom surface must be clean, flat, and flush.

Maintain Structural Baselines: Do NOT touch the existing J-hook bayonet twist-lock geometry on the Bayonet Closure. It functions perfectly on the physical prototypes
Cleanly deboss the official brand logo (minimum 0.5mm depth for MJF) and add a small geometric recessed frame on the outer shell for serialization.

📦 Mandatory Deliverables (The Complete Package)
To clear project milestones for final payment, you must deliver:
Native SolidWorks Assembly: A complete, native SolidWorks Pack and Go Zip File with fully defined 2D sketches, intact external references, and zero broken links.

Production-Ready 2D Engineering Drawings: Professionally formatted PDF and DXF drawing sheets for every single individual component, detailing critical dimensions, manufacturing tolerances for MJF, and cross-sectional assembly views.

Formal Bill of Materials (BOM): A clean spreadsheet mapping out finalized part names, quantities, exact dimensions, and material specifications (MJF Nylon 12 PA12).

Interference Verification: A native SolidWorks Interference Detection report reading "No Interferences" across the entire assembly stack while maintaining our required 0.15 mm to 0.20mm DfAM clearances.

Please do not apply if your primary experience is limited to CAD drafting or modeling. I am seeking an engineer who has personally designed complete electromechanical products from concept through prototype.

We are seeking a skilled Mechatronics/Product Development Engineer to design a compact, automated, durable product. The project involves the design of a compact electromechanical product incorporating DC motors, cable-driven mechanisms, linear actuators, bearings, and custom mechanical assemblies. Experience selecting motors, designing mechanisms, and integrating electromechanical systems is required.

The ideal candidate will have experience in mechanical design and product development, with a strong understanding of mechatronics principles. The role requires close collaboration throughout concept development, engineering trade studies, design reviews, and prototype development to produce a robust proof-of-concept design suitable for fabrication and testing.

Please include examples or screenshots of products you personally designed and briefly describe your specific engineering contributions.

This project is confidential. An NDA must be signed before detailed project information is shared.

Deliverables:
Concept development
Mechanism architecture
Motor selection and sizing
Gearbox / transmission selection
Bearing selection
CAD assembly
Detailed part design
Preliminary Bill of Materials (BOM)
Design review meetings
Design revisions

Desirable skills:
Electromechanical Design

Machine Design

Experience working directly with overseas manufacturers or preparing designs for manufacturing is highly desirable.

In your proposal, please describe the most technically challenging electromechanical product you have personally designed and your specific role on that project. Generic proposals will not be considered.

Please begin your proposal with the words "Mechanical Innovation" so I know you've read the full job posting.

Project Overview

I am looking for an experienced industrial 3D CAD modeler to recreate an aircraft drilling jig based on the reference material provided.

This model will be used strictly for visualization purposes and not for manufacturing or production. Therefore, absolute dimensional accuracy is not required, but the model must maintain correct proportions and closely match the reference material.

Scope of Work

The selected freelancer will be responsible for:

Recreating only the gray drilling jig shown in the supplied reference drawings.
Using the provided 2D technical drawings as the primary reference.
Consulting the real-world photographs whenever necessary to clarify details that may not be fully represented in the drawings.
Producing a clean, accurate, and visually convincing industrial 3D model.
What NOT to Model

Please do not recreate:

The aircraft fuselage (shown in blue).
The aircraft components shown in red.

Only the drilling jig itself is part of this project.

Modeling Requirements
Previous experience with industrial equipment, tooling, fixtures, jigs, or aerospace components is strongly preferred.
The model should accurately preserve the overall geometry and proportions of the real assembly.
Since this model is intended for visualization only, there is no need for manufacturing-grade tolerances or exact dimensions.
Please create an optimized, efficient mesh. Avoid unnecessary geometric complexity and excessive polygon counts.
Smooth curved surfaces (particularly around clamps, brackets, and mounting hardware) are expected, but the model should remain lightweight and easy to manipulate.
Favor clean topology and an efficient polygon budget rather than an unnecessarily high-poly model.
Deliverables

Preferred output formats:

.OBJ
.CATPart (preferred if available)

OVERVIEW
We make a premium outdoor consumer product with wood cladding and formed stainless steel corner panels. Each panel wraps a rounded corner and continues as a flat section along the wood face, with a decorative cutout in the flat section.

Problem: the current CAD models the panel as one blended surface with no proper bend definition. Our fabricator formed it by guesswork, and the section that should sit flat along the wood came out curved, with a visible gap and shadow. It needs to look clean and sit perfectly flush.

We have already diagnosed the root cause and have the target geometry worked out. You will get the full CAD and a clear spec sheet once hired. This post stays high level on purpose.

SCOPE OF WORK
1. Rebuild the wrap panel as a proper sheet metal part: curved only where it wraps the corner, dead flat where it lands on the wood, with defined bend and tangent lines the factory can actually follow.
2. Adjust the panel edge geometry per our spec so the flat section stays consistent from top to bottom.
3. Re-angle the existing decorative cutout to match the corrected edge.
4. Apply the corrected geometry to the remaining corners (symmetric).
5. Deliverables:
a. Updated parametric part files plus STEP exports
b. Flat pattern DXF for each panel with the rolled zone clearly marked
c. 2D manufacturing drawing (PDF) with dimensions, bend and tangent lines, material and thickness, springback note, and a flatness tolerance on the flat zones
d. Assembly fit check against the provided body model, confirm full contact on the flat zones
6. One revision round included.

WHAT WE PROVIDE AFTER HIRE
STEP file of the full assembly, a one page spec sheet with every target dimension, and reference photos of the as built part.

REQUIREMENTS
Proven sheet metal design for fabrication experience: rolled and large radius bends, springback compensation, flat patterns. Stainless experience preferred. SolidWorks preferred, Fusion 360 acceptable if you can deliver the formats above.

I have started the design and the bulk of the work has been completed. I now need someone to finish the design and start creating drawings for piece parts.

The project needs to be done in SolidWorks 2023.

See video of what I need.

I need a mechanical enclosure designed in SolidWorks for an ESP32 DevKit V1
board with a DHT22 temperature/humidity sensor. This is a functional
enclosure for a real device, not a concept render — dimensional accuracy
and printability are the top priorities.

DELIVERABLES:
1. Base enclosure body (SolidWorks .SLDPRT) — walls shelled to 2mm,
mounting bosses for the ESP32 board at correct hole spacing pulled
from the official datasheet
2. Separate lid part (.SLDPRT) with through-holes aligned to the base
standoffs
3. Cutout for USB-C port (positioned to match the actual board's port
location/height) and a ventilation slot pattern
4. Fillets on all outer edges (clean, non-sharp finish)
5. A full 2D engineering drawing (PDF) with dimensions, ±0.1mm tolerance
called out on the mounting holes, and a completed title block
(material: PETG or ABS, scale, date, designer name)
6. One rendered image (PNG, white background, shaded-with-edges or
PhotoView 360) suitable for a portfolio
7. STL export of both parts, sliced in Cura or PrusaSlicer, with a
screenshot of the sliced preview showing no obvious print errors
(supports, overhangs, etc.)

REQUIREMENTS:
- All dimensions must be pulled from the actual ESP32 DevKit V1 and
DHT22 datasheets — Please reference the datasheet
source you used in your delivery notes.
- Units in mm (MMGS).
- Enclosure should comfortably fit both components with reasonable
clearance — you can propose exact outer dimensions, but I'd expect
something in the range of 70mm x 50mm x 25mm unless your datasheet
research suggests otherwise.
- Final native SolidWorks files (not just STEP/STL) must be included
so I can edit them later.

WHAT I'LL PROVIDE:
- Confirmation of exact ESP32 board variant if there's ambiguity
- Feedback within 24 hours on any milestone submission

IDEAL FREELANCER:
- Strong SolidWorks portfolio with enclosure/housing design examples
- Experience designing for FDM 3D printing (tolerances, wall thickness,
overhangs)
- Comfortable working from component datasheets independently

Please include 1-2 examples of past enclosure work in your proposal.

​Hi Naveed,

​I am looking to commission 3D models for two different shoe designs (see attached images) intended for printing on a Bambu Lab machine.
​For both designs, I need functional, wearable products with the following requirements:

​Technical Accuracy:
To ensure a proper fit, I can provide 3D shoe lasts (or reference files) for you to build upon. Please let me know if you are comfortable working with these.

​Sizing:
Each design needs to be scaled to cover sizes 36 through 41. Please advise if you can provide the source files for easy adjustment or if you can supply the individual files for each size.

​Multi-material/Dual-density:
The designs must feature a flexible "upper" for comfort and a rigid heel for stability. Please advise on the best materials (e.g., using different TPU Shore hardnesses) to achieve this balance.

​Printability: The models must be structured for seamless multi-color printing and optimized for FDM, minimizing supports while maintaining structural integrity.

​Are you experienced with 3D-printed footwear design? I’d love to discuss the feasibility of this project and your process.

​Best regards,

​Axel

need help in applying right boundary conditions. Its a CFD studies for the external equipment. Need to study the wind. how the wind affects the outdoor equipment(generators etc)

I’m looking for a talented mechanical/3D product designer to create a custom 3D-printable mount that will securely hide my Apple Mac mini M4 underneath my kitchen table.

The goal is to make it look like it belongs there—not just a simple shelf screwed underneath the table. I want it to integrate with the existing table structure and use the table itself for strength and support.

I’ve attached several photos with measurements and sketches showing my concept.

⸻

Design Concept

My idea is to create a fork-shaped mounting bracket that wraps around the existing wooden cross member of the table.

The mount would:

* Wrap around the lower cross member using a fork/clamp design.
* Travel vertically up alongside the table leg.
* Continue upward until it reaches the underside of the tabletop.
* Turn 90 degrees and hook over/against the underside of the table to create a very rigid brace.
* Extend horizontally toward the edge of the table where it supports a shelf for the Mac mini.

This creates a very strong structure while avoiding permanent modifications to the table.

⸻

Additional Support

One of the table rails runs directly beside the shelf.

I intentionally left room beneath that rail so I can install zip ties around it to provide additional support and prevent movement.

The mount should be designed with built-in openings or channels for zip ties.

⸻

Shelf Requirements

The shelf should fit a Mac mini M4.

Shelf Internal Dimensions

* Width: 7 in (178 mm)
* Depth: 9 in (229 mm)
* Height clearance: 3 in (76 mm)

The shelf should have:

* Open rear for cables
* Plenty of ventilation
* Small front lip to prevent sliding
* Easy access for connecting cables

⸻

Important

The table is solid wood, and I do not want to drill unnecessary holes.

I’d like the mount to rely on the table’s existing beams and geometry as much as possible.

The bracket should be rigid enough that the Mac mini cannot bounce or vibrate when the table is moved.

⸻

Deliverables

Please provide:

* Fusion 360 preferred (or SolidWorks)
* STEP file
* STL files ready to print
* Parametric source files
* Assembly drawing
* Exploded view (if multiple pieces)
* Hardware list (if bolts or inserts are required)

⸻

Design Goals

I’m looking for something that is:

* Clean
* Minimal
* Strong
* Elegant
* Easy to install
* Easily removable without damaging the table
* Designed specifically for 3D printing

⸻

Printing

I own multiple Bambu Lab printers and can print large parts.

Preferred materials:

* PETG
* ASA
* ABS

Please design with FDM printing in mind.

⸻

Attached

I’ve included multiple photos showing:

* Overall underside of the table
* Measurements
* Cross member dimensions
* My concept sketches
* Shelf location
* Proposed zip tie locations

Please review all images before submitting a proposal.

⸻

Bonus

If you have experience designing structural 3D printed brackets, furniture mounts, or Apple accessory mounts, please include examples of similar work in your proposal. I appreciate designers who think through both strength and aesthetics.

One Black Diamond Hot Forge carabiner, one Black Diamond nut (any size), one Black Diamond C4 cam (any size), and one Black Diamond Hot Forge quickdraw.

While the shape and iconic details are necessary, the design will have no moving parts. Essentially a child's toy version of these items for the purpose of injection molding.

Files must be editable for future modification, and ownership of the files will remain solely with myself.

Communication through video conference, phone, and email will be used to clarify and coordinate. Orthographic sketches of each item will be sent for further clarification.

We are looking for talented Solidworks or Siemens NX modelers who can help us model mechanical components for a project we're working on.

Ideal applicants have great control over Solidworks or NX and also understand how to make good drawings.

Pay is up to $80/hr depending on modeling skill!

We're building a library of realistic CAD-based engineering workflows for an AI training data project. Looking for mechanical engineers with real automotive or aerospace design experience to package up original CAD work into structured workflows.
What's involved:
Each workflow package = one CAD file (yours, real, complex — bracket, housing, assembly, etc.) plus:

Design context (where it fits in the system, function, constraints)
4–5 realistic change requests (the kind you'd actually get as an ECR)
Step-by-step implementation walkthrough for each change
Validation/review steps you'd actually run

Who we need:
3+ years hands-on industry design experience (auto or aerospace), not academic/managerial
Comfortable in FreeCAD, or SolidWorks/CATIA/NX with ability to export clean STEP files
You must own full rights to the files, no employer/client IP, nothing export-controlled

Project Overview
We are seeking a 3D designer or studio to create a set of three stylized treasure chest assets for use within a mobile application. At this stage, we are gathering availability, estimated timelines, and pricing from qualified designers before moving into the full design phase.
Additional creative direction, branding assets, and reference materials will be shared with the selected designer.
Scope of Work
Design three realistic and unique 3D treasure chests that represent a clear progression in value and visual appeal.
The three assets should include:
• Level 1: Basic treasure chest
• Level 2: Mid-tier treasure chest with enhanced details
• Level 3: Premium/extravagant treasure chest with the highest level of detail and visual impact
The treasure chests should align with the Fish Shop/fishing-themed brand and feel cohesive as part of the same product family while becoming increasingly exciting and rewarding as users progress through the app.
Intended Use
These assets will be used within a mobile application and should be optimized for digital use while maintaining a polished, high-quality appearance. Accepted file formats include Filmbox (.fbx) or GL Transmission Format (.glTF). Each treasure chest design will need to be separated into top and bottom for future animations.
Information Requested
Please include the following in your response:
• Estimated cost for designing all three assets
• Estimated production timeline
• Your earliest availability to begin
• Relevant examples of similar 3D product, game, or mobile app assets you've created (portfolio or website)
Timeline
This project is time-sensitive. Our ideal turnaround is 1–2 weeks, though we welcome your recommendation based on the scope of work.
Next Steps
Following initial pricing and availability, we will provide additional project details, creative references, branding guidelines, and technical requirements to the selected designer(s).

I am looking for an experienced mechanical CAD designer or machine design drafter to prepare professional fabrication drawings for a small steel fabrication project.

This project is intended to produce fabrication-ready drawings for a welding shop to use for fabrication, not conceptual sketches or architectural drawings."

The project consists of approximately four fabricated steel assemblies made primarily from Schedule 40 steel pipe and steel plate. The components include welded sleeve assemblies, corner elbows, support brackets, and clamp collars.

The first phase of this project is for the elbow piece ONLY.

I have already prepared detailed written fabrication specifications, dimensions, quantities, materials, and functional descriptions. I will provide these documents to the selected freelancer.

Deliverables should include:

• Professional fabrication drawings (PDF)--this is the more important deliverable.
• 3D CAD models (STEP format preferred)
• DWG and/or DXF files
• Assembly drawings where appropriate
• A plain-text description of each part listing all dimensions, materials, holes, welds, and notes. This is important because I am blind and review technical documents using a screen reader.

The drawings should be suitable for fabrication by a competent welding or machine shop.

The initial engagement will be for one representative part -- the elbow ONLY. If the work product is satisfactory, the remaining parts will be awarded as additional milestones.

Required Skills:

Mechanical CAD Drafting

Machine Design

Steel Fabrication Drawings

Weldment Design

SolidWorks, Fusion 360, Autodesk Inventor, AutoCAD, or equivalent

Experience preparing shop drawings for welding and fabrication

Preferred Qualifications:

Experience designing fabricated steel assemblies

Experience with Schedule 40 pipe structures

Experience creating fabrication drawings rather than architectural drawings

Ability to communicate clearly and ask questions if any dimensions or details require clarification

Project Type:

One-time project with the possibility of additional related work.

Pricing:

Please submit either:

A fixed-price proposal for the initial part, or

Your hourly rate along with an estimate of the hours required.

Attachments--

The selected freelancer will receive:

Complete written fabrication specifications

Design standards

Fabrication requirements

Part descriptions

Questions for Applicants:

1. Which CAD software will you use?

2. How many years have you prepared fabrication drawings for welded steel assemblies?

3. Please provide one or two examples of fabrication drawings or machine parts you have designed.

4. Are you comfortable producing both 3D models and detailed fabrication drawings?

5. Do you have experience designing weldments made from Schedule 40 pipe?
