3D Prototype Model Creation

I’m looking for a skilled 3D modeler who can take my product concept and turn it into a clean, production-ready CAD file. The model will be used strictly for prototyping and manufacturing, so I only need the basic structural geometry used for a cast mold—no surface texturing, no intricate mechanical assemblies, and no moving parts.

You’ll receive sketches, key dimensions, and any reference photos I have. From there, I’d like you to build the part in a common format such as glTF, STEP and DXF. This file will need to be sent to China for building cast molds. Blender is preferred as it's what we use for our products, buit SolidWorks, Fusion 360 or similar parametric software can be used.

Deliverables
• Fully parametric 3D file (glTF, STEP and DXF)
• A quick viewport render or screenshot to confirm overall shape before final hand-off
• Source file from your native software so I can make future tweaks if needed

I’ll review the initial draft for dimensional accuracy and overall fit; once approved, you can finalize and send the export. Turnaround within a few days would be ideal, but let me know what’s realistic for you. Message me with a brief note on your experience with modeling for cast molds and a link to a sample that shows clean, watertight geometry.
