Freelance Solidwork designer jobs

Need help refining a CAD packaging design for a plant holder based on an attached sketch. The current version shows tabs on the side, which I would like to eliminate. The final design should support at least 60 grams and securely hold one pot measuring 16cm wide by 14cm high. Please review the attached files and suggest a revised design that meets these requirements while keeping the overall look clean and functional.

Mechanical Engineering Scope — Automated Vertical Storage/Handling System
A conceptual SolidWorks model exists for a large automated vertical storage/handling machine. The goal is to convert the concept into a fabrication-ready engineered design suitable for structural steel fabrication, hydraulic actuation, robotic plasma cutting, welding, assembly, and field installation.
The engineer shall review and refine the existing CAD, preserve the intended machine architecture where practical, and modify member sizes, brackets, pins, weldments, hydraulic components, and local geometry as required by analysis and manufacturability.
Structural work shall include FEA and supporting calculations for the main frame, vertical lift structure, carriers, lift trolley, support/capture features, guide system, pins, sleeves, brackets, and critical joints. Load cases should include gravity, maximum payload, eccentric loading, asymmetric lift, hydraulic stall/relief loads, dynamic factors appropriate to slow machinery, and credible fault conditions.
Analysis should address:
- stress and deflection;
- global and local buckling;
- torsion;
- HSS wall effects;
- pin bearing and tear-out;
- weld and bolted-joint capacity;
- local load transfer;
- failure-mode and safety-factor identification.
The design should be optimized for low weight and simple fabrication rather than made unnecessarily heavy.
The lift system is expected to handle approximately 20 kip total load over roughly 120–135 in of vertical travel. Direct hydraulic lifting is preferred where practical. Candidate architecture consists of two servo synchronized long-stroke cylinders.
The engineer shall complete the hydraulic design, including cylinder sizing, pump displacement, motor/servo requirements, operating pressure, relief settings, reservoirs, load-holding provisions, hose and fitting sizes, filtration, pressure sensing, position feedback, synchronization, and failure response. The current control direction uses electrically driven reversible hydraulic pumps, potentially one pump per cylinder.
Mechanical fail-safe features should also be developed, including positive load support when stationary, continuous carrier capture/alignment, and protection against abnormal descent or skew.
The final design shall be reduced to fabrication-ready drawings with dimensions, tolerances, materials, weld symbols, machining requirements, purchased-component interfaces, and inspection dimensions.
Applicable structural members shall also be prepared for Lincoln Electric PythonX or equivalent robotic plasma fabrication. This should include PythonX-compatible NC/CNC files, or other required machine files, for cuts such as holes, slots, copes, miters, fishmouths, end cuts, and weld-prep geometry. Parts not suited to PythonX should be identified for tube laser, plate laser/plasma, machining, turning, or conventional fabrication.
Final deliverables should include the updated 3D CAD assembly, part models, FEA report, supporting calculations, hydraulic schematic and component schedule, fabrication drawings, BOM, weld schedules, PythonX NC/CNC files, DXF/STEP files as required, assembly/alignment instructions, and recommended proof-load and functional test procedures.
The objective is a manufacturable, serial-production-ready design, not simply a high-level design review.

EE and programing will be provided by other engineers, as needed.

design job i will interested for me. And hoply work for the disign.

I need a designer to turn my sketches and specs into production-minded CAD and 3D-printable prototype files. The product is a consumer accessory made of silicone and stainless steel, including a hinged case, a strap, and small threaded metal parts.

This is a two-phase project. Phase 1 is the case + strap, which this post covers. Phase 2 is the threaded metal parts, to be scoped later. I’ll share a rough model request first so we can check direction early.

Deliverables: STEP and STL files plus a parametric source file (Fusion 360 or SolidWorks). I’ll prototype on a Bambu P1S, so FDM-aware design is a plus.

An NDA is required before I share the full brief. Please include a portfolio link to similar work (ideally molded or hinged parts) and your timeline.

Hi! I would like to talk to you about a project I’m currently developing, and I’d love to get your technical opinion on it.

I’m studying dental prosthetics in France, and I’m working on an innovative concept: a smart, connected dental mouthguard designed to monitor certain phenomena during sleep.

The idea is to develop a mouthguard that could collect data related to bruxism (teeth grinding and clenching), snoring, and potentially certain indicators associated with sleep apnea.

My goal is to combine my knowledge of dental prosthetics with electronics, sensors and connected technology to create a functional prototype.

I already have an idea of the physical design and how I would like the device to work, but I need help understanding the technical side: which sensors could be used, how the electronics could be integrated into such a small device, how to collect and transmit the data, and what is realistically achievable with current technology.

I’m not necessarily looking for someone to manufacture the entire product right away. First, I’d like to discuss the concept with someone who understands electronics and product development, explore the technical possibilities, identify the challenges and determine the best way to build a first prototype.

I’m looking for someone who could genuinely help me develop this idea step by step. If we work well together, I’d be interested in building a longer-term collaboration.

I know this project involves technical challenges, and I’m open to suggestions and alternative approaches. What matters to me is finding a realistic solution and turning the concept into something tangible.

Would you be interested in discussing the project with me and sharing your thoughts on its feasibility?

I’d be happy to tell you more about the concept once we’ve established an appropriate confidentiality agreement.

I'm developing an adjustable door strike plate: a base plate that mounts to the door jamb, plus a second plate with teeth that interlock with the base so the latch engagement point can be shifted.

Similar products exist. Their main weakness: when the door is latched and force is applied (door pushed or pulled, weatherstripping pressure), the latch loads the toothed plate and the interlock between the two plates isn't strong enough to hold position. The plate slips. Solving that holding strength is the entire point of this project.

The initial ask:
- Review the reference product (video attached)
- Propose 2 to 3 interlock concepts with sketches and a short explanation of why each resists slipping better. This product will be stamped so the design must factor that in.
- Note tradeoffs: holding strength, adjustment range, ease of install, stamping cost

If we can find an improved design, then there will be future work to create the STL and mechanical drawings for prototyping and manufacturing. Everything hinges on being able to create a successful new design in the first place though.

Project Overview:
I am developing a metal kitchen utensil/cutting tool and need an experienced Mechanical Engineer or Industrial Designer to convert existing sketches, dimensions, and reference concepts into production-ready 3D CAD models and 2D fabrication drawings.

Confidentiality Requirement:
Because this product features proprietary geometry, signing a standard One-Way NDA is required before sketches and dimensions are shared. All intellectual property and native design files will remain 100% client-owned upon payment. You must agree not to display this project in any public portfolio.

What We Are Designing:
A handheld stainless steel food preparation tool featuring specific blade bevels, curved geometry, and ergonomic gripping surfaces. The design must account for real-world metal fabrication methods (e.g., laser/waterjet cutting, sheet metal forming, CNC machining, and blade grinding) as well as structural rigidity.

Project Milestones & Deliverables:
• Milestone 1 (50%): Initial 3D CAD & 3D Print Mockup File
- Create parametric 3D model based on provided sketches and dimensions.
- Deliver a high-resolution .STL file for rapid 3D printing to test hand ergonomics and motion.
• Milestone 2 (50%): Revisions & Final Production Package
- Incorporate minor ergonomic/dimensional adjustments after the 3D print test.
- Deliver final .STEP (AP214) file ready for machine shop / manufacturer quoting.
- Deliver native parametric CAD file (.SLDPRT or .F3D with full feature tree intact).
- Deliver fully dimensioned 2D Engineering Drawing (.PDF and .DWG) calling out overall dimensions, radii, material thickness, bevel/grind angles, and standard tolerances.

To Apply, Please Include:
1. Which CAD software you use (SolidWorks or Fusion 360 preferred).
2. A brief example of a metal product, blade, or consumer hand tool you have designed for manufacturing.
3. Confirmation that you are comfortable signing an NDA and keeping this work off your public portfolio.

Hi Luciano,

I'm developing a handheld electronic scalp stimulation device designed specifically for people with braids, cornrows, locs, and other protective hairstyles.

The concept uses a small, seamless, rounded metal tip that delivers adjustable vibration directly to the scalp without catching or disturbing the hair.

I've attached a product design brief and visual renderings outlining the concept.

I'm looking for an engineer who can help turn this into a functional, manufacturable prototype, particularly the vibration mechanism and seamless metal tip.

Could you let me know whether this falls within your expertise, if you've developed similar electronic products, and what you would charge for an initial feasibility assessment?

I'd like to start with a small project before moving into full development.

Thank you!

We are developing a new desktop corporate product catalog and need a fully mechanical, battery-free, ultra-thin image switching mechanism.

System Concept (Please See Attached Images)

•⁠ ⁠Our catalog consists of a 35 × 25 cm landscape-oriented panel.
•⁠ ⁠As shown in Image 1, the front cover containing our company information features a fixed 11 × 9 cm viewing window in the marked area.
•⁠ ⁠This window will display one product photograph at a time.
•⁠ ⁠The user will move to the next photograph by gently rotating a scroll wheel, similar to the wheel on a computer mouse, located directly below the viewing window.
•⁠ ⁠The photographs will advance in a continuous infinite loop, without requiring rewinding or resetting.
•⁠ ⁠Image 2 shows the area available for installing the mechanism. The entire internal area of the 35 × 25 cm panel can be used for the mechanical design. A printed front cover containing our company information will be placed over it.

Technical Requirements and Parameters

1.⁠ ⁠Overall Thickness: Our target total product thickness is 4–6 mm, including both the front and back covers.
2.⁠ ⁠Capacity: The system must be capable of holding up to 25 product photographs.
3.⁠ ⁠Ergonomics: The scroll wheel must operate extremely lightly and smoothly. The user must be able to advance to the next photograph with a very short, effortless finger movement, without having to rotate the wheel repeatedly.
4.⁠ ⁠Image Alignment: With every transition, the photograph must align perfectly within the viewing window and must never remain partially visible or misaligned.
5.⁠ ⁠Hygiene and Durability: The exterior surface must be flat, easy to wipe clean, and protected against liquid and dust ingress.
6.⁠ ⁠Development Objective: We want the most suitable mechanical solution to be developed within the specified dimensions. We are open to alternative recommendations regarding material selection and mechanism design.

The designs shown in the attached images are intended only to illustrate the operating concept. We are open to thinner, simpler, and more reliable solutions.

How Will It Work? (Simple Explanation)

There will be a photo viewing window in the center of the catalog, with a small wheel similar to the one on a computer mouse directly underneath it.

As the user gently rotates this wheel with their finger, the photograph will change. Each time, the new photograph must be fully visible and must never stop halfway.

The system will hold up to 25 different photographs, and after the last photograph, it will return to the first photograph.

I am a mechanical engineer who currently works in the insurance industry as a technical consultant. Some may refer to me as a forensic mechanical engineer. I have a background in automotive, where I have worked for major companies, most recently Tesla in 2017. I worked as a test engineer before my current job. Over the past couple of years, I have found my self longing for exposure to the tech industry. I have friends who work in tech and it has been fruitful both growth-wise and financially. I am feel like an average engineer, who has not quite made an impact or unlocked my fullest potential. There are some gaps in the opportunities I wish I could have had, but I am optimistic that I can still work towards those experiences. What I lack from day to day is mentorship and feedback from peers, where I can gauge how my career is progressing. In short, I would like to give the tech industry another shot. However, I am lacking in a few areas.

I am looking to consult with a fellow mechanical engineer who has worked or currently works at Tesla, SpaceX, Google, Apple, Meta, Nvidia, Microsoft, etc. Ideally the first of the two. Someone with management or team leadership experience. Preferably someone with 10-20 years of experience and has worked as a Staff, Senior Staff, Principal, or higher level. What I would like to do is create projects for myself and review my work with my mentor, where I can get feedback, help, and the technical advance I am looking for.

In the coming weeks, we would have meetings on a weekly basis, where we work on solving problems, researching, and developing the work. I would like to create skills in CAD using tools like SolidWorks, CATIA, and related tools. Software and tools that are commonly used at the company. The job postings I have been scoping often include the main keywords, "Test Engineer" and "Mechanical Design Engineer" across multiple divisions at each company.

Industrial Product Designer / Mechanical Engineer – Modular Caravan Storage System

I'm looking for an experienced product designer or mechanical engineer to help develop an adjustable modular storage system for caravan and RV overhead cupboards.

The idea came from my own caravan, where I've noticed a lot of unused space, particularly in the upper sections of the cupboards. I'd like to create a practical, lightweight storage solution that maximises this space while keeping items organised, accessible and secure during travel.

What I'm looking for:

Adjustable sizing to accommodate different cupboard widths, heights and depths.

Modular shelves, trays or dividers that can be repositioned or removed.

Lightweight aluminium supports or framing, potentially combined with durable plastic components.

A secure, preferably no-drill installation system.

A practical design that is easy to install, clean and manufacture.

Consideration for weight, durability and movement during caravan travel.

Initial Reference Measurements

I've measured two overhead cupboards in my Crusader caravan:

Cupboard 1: 550 mm W × 380 mm H × 240 mm D (approximately 200 mm usable depth).

Cupboard 2: 440 mm W × 300 mm H × 270 mm D.

These measurements are a starting point. The goal is to develop a modular system that can adjust to suit a wider range of caravan and RV cupboard sizes.

What I need from the designer:

Initially, I'd like to explore a few design options, suitable materials and adjustable mechanisms, followed by preliminary 3D CAD designs and recommendations for prototyping.

Ideally, I'm looking for someone who can also assist with the next stages, including detailed CAD drawings, physical prototypes, testing and eventually a manufacturer-ready tech pack.

Experience with modular products, aluminium and plastic components, adjustable mechanisms and design for manufacturing would be highly regarded.

I'm open to alternative materials and creative engineering solutions that could improve the product or make it more cost-effective to manufacture.

Please share examples of similar products you've designed, your estimated timeframe and what you would include in the initial design stage.

I have a concept board, photographs and measurements available to share.

I'm looking for someone who can contribute practical ideas and help develop this into a commercially viable product.

Louvreclad designs and manufactures architectural louvres, façades and solar shading systems in Australia. We are seeking an experienced visualisation specialist to create premium, photorealistic product renders suitable for architectural presentations and marketing.

The initial project

Our first project involves our Aerion Series A1 performance louvre. We can provide:

A 3D model created in SolidWorks.

Detailed PDF shop drawings.

Photographs of a manufactured sample.

Specified colours and finishes.

We have trialled an AI-generated render, but need a substantially higher standard of geometric accuracy, material realism, lighting and overall presentation.

The supplied SolidWorks model should form the basis of the visualisation, with the drawings and photographs used to verify details and guide the material appearance.

What we need

Import and prepare the SolidWorks model for rendering, retaining the correct blade profiles, spacing, panel joints, framing and sill details.

Apply realistic powder-coated aluminium materials in the specified finish.

Develop lighting and camera angles that clearly communicate the product’s depth and detail.

Produce crisp, consistent geometry without warped blades, uneven spacing or artificial textures.

Use AI enhancement where it improves the result while preserving the product’s design.

We welcome a combination of conventional 3D rendering and AI tools. The priority is an accurate, convincing final image.

Initial deliverables

A preview for approval of geometry and camera angle before final rendering.

One high-resolution hero render of the complete assembly.

One close-up render showing blade geometry, material finish and framing detail.

Final images at a minimum of 4K resolution in PNG or TIFF format.

Editable rendering scene and associated assets, with any licensing restrictions disclosed.

Two rounds of revisions.

Please provide a fixed-price quote for this initial scope.

Required experience

A strong portfolio of photorealistic architectural or manufactured-product renders.

Experience importing SolidWorks models or suitable exchange formats into rendering software.

Ability to interpret architectural shop drawings.

Experience visualising detailed metalwork, façade systems, screens or louvres.

Strong material, lighting and composition skills.

To apply, please include

Two or three relevant examples, ideally featuring architectural metalwork or detailed façade products.

An example showing a source CAD model alongside the finished render.

Your proposed workflow, including rendering software and any AI tools.

Your preferred SolidWorks or exchange file format.

Your fixed-price quote, turnaround time and included revisions.

Confirmation of the editable files and commercial usage rights included.

Ongoing opportunities

Successful completion may lead to further product renders and architectural visualisations across the Louvreclad range.

All supplied models, drawings and product information are confidential and must not be published, reused or included in a portfolio without written permission.

Hello,

I am developing a new three-piece decorative plumbing product designed to conceal exposed 1/2-inch PEX tubing and its connection to a shutoff valve.

I have concept illustrations and preliminary dimensions. I need an experienced mechanical product designer to turn this concept into functional CAD models suitable for 3D printing and eventual plastic injection molding.

The product consists of:

A 5-inch trim-to-fit split sleeve.

A 2.750-inch-diameter split escutcheon designed to completely cover an existing wall escutcheon, with a receiving socket approximately 0.375 inches deep.

A split collar approximately 0.750 inches long to conceal PEX crimp rings or stainless-steel pinch clamps.

All three components must be installable without disconnecting existing plumbing.

I would like a fixed-price quote for initial CAD development, snap-fit design, basic dimensional drawings, and printable prototype files.

Please provide examples of similar plastic products you have designed, particularly products using snap-together connections.

I would also require ownership of the completed design and editable CAD files.

Thank you.

We need a freelancer to convert a large DWG model into a small-scale 3D printable version.

The source file is a detailed DWG / 3D model of a full-size build. We need it scaled down to approximately 4.5" wide (the actual model is 16' x 8' x 4') and prepared for printing. At this scale, a lot of the fine detail in the original won’t survive, so we need someone who knows how to simplify intelligently: keep what reads visually, remove or thicken what won’t print, and make sure the final model is structurally sound.

Scope of work:

Import and clean up the source DWG / 3D model
Scale to target size and simplify geometry as needed
Thicken thin walls and small features to meet minimum printable thickness
Remove or consolidate details that won’t hold up at scale (hardware, fasteners, internal components, etc.)
Make the mesh watertight / manifold with no errors


Deliverables:

Print-ready STL (or 3MF) files for each part
Native working file (e.g. Rhino, Fusion 360, Blender, SolidWorks)
