I will create 3d mechanical design and prototype from your product


About this gig
ABOUT MY GIG
Have a product idea, sketch, or reference image and need it turned into a manufacturable 3D design? I help startups, inventors, and brands convert product concepts into accurate 3D mechanical models and functional prototypes, ready for 3D printing or manufacturing.
With 5+ years in mechanical CAD, I use SolidWorks, Fusion 360, and DFM standards so your design isn't just pretty it works, fits, and can be built.
WHAT YOU GET:
- Accurate 3D CAD model from your photo, sketch, or sample product
- Functional prototype design (moving parts, assemblies, tolerances)
- 3D printable STL/STEP files
- Manufacturing ready technical drawings on request
- Free consultation before you order
WHO I WORK WITH: Inventors, hardware startups, and businesses that need to go from "idea" to "physical prototype" fast and correctly.
WHY WORK WITH ME: I don't just model shapes I engineer parts that survive real world use, tooling, and assembly. Every project includes a design review so problems are caught before you spend money on manufacturing.
Message me with your product idea or reference image before ordering so I can scope it correctly and recommend the right package.

FAQ
I only have a photo, not a sketch can you still design it?
Yes, I can reverse engineer a 3D model from clear reference photos with visible dimensions or a known reference object for scale.
Will the file work with my 3D printer or manufacturer?
Yes, I deliver STL for printing and STEP for CAD/manufacturing use, compatible with virtually all software and printers.
Do you design moving/functional parts, not just static shapes?
Yes, Standard and Premium packages include functional assemblies with proper clearances and tolerances.
Can you add manufacturing drawings later if I only order Basic?
Yes, drawings can be added as an extra or by upgrading to Standard/Premium.
