Custom Prototype Design Service: Idea, Sketch, or Drawing to 3D File
Transform rough concepts into precise 3D CAD files ready for prototyping. Our custom prototype design service converts your sketches, drawings, or ideas into editable models for manufacturing.
Share your initial drawings or descriptions and we prepare clean, manufacturable 3D files. This service focuses on early-stage conversion so you can move quickly into quotes for 3D printing or CNC.
Files We Accept
Send hand sketches, PDF drawings, napkin concepts, or basic images. We return STEP, IGES, or STL files suitable for prototype manufacturing. A $200 project minimum applies.
How It Works
- Upload your sketch or idea with notes on dimensions and function.
- We review and confirm scope within one business day.
- Receive the first 3D file version plus pricing guidance in 24-48 hours.
- Request revisions or move directly to prototype production.
Is This Service Right for You?
Choose this option when you have an idea or drawing but no 3D file yet. It is ideal for inventors and product teams preparing their first prototype run.
