I will model your product idea into a 3d printable prototype design


About this gig
Have an idea for a product, gadget, or invention but nothing built yet just a concept, a sketch, or a "picture it in your head" description? I'll turn that into an actual 3D CAD model you can hold, test, 3D print, and use to explain your idea to manufacturers, investors, or a patent attorney.
This is concept-to-model work: we start with what the product needs to do, I ask the questions that matter (size, moving parts, materials, how it's used), and I build a model that actually reflects real-world function not just a pretty shape that can't be made.
What you get: 3D model built from your concept, sketch, or description Design refined for 3D-printability (or manufacturing, if that's the end goal) STL for prototyping + STEP for future engineering/manufacturing use Basic technical drawing of the concept on request One revision round included on every package
This is honestly my favorite kind of project there's nothing better than watching an idea that only existed as a sentence turn into a file you can actually print and hold. Message me with your concept, even if it's rough, and I'll tell you what I'd need to model it.

FAQ
I've never made a technical drawing or CAD file how do I explain my idea to you?
A voice note, a hand sketch, reference photos of similar products, or just a written description works fine. Part of this gig is me asking follow-up questions to fill in the gaps before I start modeling, so nothing needs to be polished going in.
Can you make it printable on a home 3D printer?
Yes I'll design with your printer's constraints in mind (overhangs, wall thickness, part size) if you tell me your printer type and build volume in the order requirements.
Is this good enough to show a manufacturer or use for a patent application?
The Premium package includes a dimensioned drawing sheet suitable as a starting reference for manufacturers or attorneys. I'm not a patent professional, so for anything patent-filing-specific, this should be treated as supporting documentation, not a legal deliverable.
What if my product has moving parts?
Let me know in the requirements — I can model separate components with correct clearances so they fit and move as intended, though full mechanism engineering (springs, motors, etc.) may need to be scoped as a custom order.
