About this gig

Do you have a physical part, 3D scan data (STL/OBJ), or old drawings but no original CAD file? I specialize in reverse engineering and CAD conversion, turning your references into accurate, clean, and editable 3D models.


What I offer:

- Convert STL/OBJ mesh files into solid CAD models (STEP, IGES, etc.)

- Reverse engineer mechanical parts from photos or sketches

- 3D modeling and file format conversion


Package Guide:

- Basic ($50): Simple parts with basic geometry (pads, brackets, simple housings).

- Standard ($100): Complex parts with multiple features, curves, or small assemblies.


Note: I provide digital files only. No 3D printing or physical prototyping is offered. Contact me before ordering to confirm your part complexity.


Delivery style preference

Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.
