About this gig
Do you have an STL, OBJ, mesh, scan, or old 3D file that you need converted into clean editable CAD?
I will reverse engineer your existing 3D model into an accurate STEP/STP CAD file for replacement parts, prototyping, CNC preparation, or 3D printing.
I can help with:
- STL to STEP conversion
- OBJ or mesh to editable CAD
- Reverse engineering mechanical parts
- Replacement part recreation
- Mesh cleanup and geometry repair
- 3D printable STL files
- STEP, STP, IGES, STL, OBJ and DXF files
- Basic technical drawings
- CAD modifications and dimension changes
This service is suitable for product developers, repair businesses, makers, manufacturers, engineers, and 3D printing projects.
Please send your STL, OBJ, scan, reference images, measurements, or existing CAD file before ordering complex parts so I can check the geometry and recommend the right package.
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.

I help product developers, manufacturers, inventors and hardware startups turn sketches, STL files, measurements and existing parts into accurate 2D and 3D CAD files.
I specialize in STL/OBJ to STEP conversion, reverse engineering, 3D-print-ready models, product enclosures, replacement parts and manufacturing drawings.
My focus is clean geometry, accurate dimensions and practical files ready for prototyping, 3D printing or production.
Deliverables can include STEP, STL, DXF, DWG, PDF and editable CAD source files depending on your project.
FAQ
Can you convert any STL file into STEP?
Most STL and OBJ files can be recreated or converted, but complex organic meshes may require different methods. Send the file first and I will check it.
Will the STEP file be editable?
Yes. For reverse-engineered packages, I create clean CAD geometry designed to be easier to edit than a raw mesh.
Can you recreate a broken replacement part?
Yes. Send clear photos, measurements, sketches or scan data. I can model replacement parts for 3D printing or further manufacturing.
Can you modify my existing STL?
Yes. I can resize, repair, adjust dimensions, add or remove features and prepare the model for printing.
Which files can you deliver?
STEP/STP, STL, OBJ, IGES, DXF, DWG and editable CAD source files depending on the project.
Do you work from photos or measurements?
Yes, especially for replacement parts. Accurate measurements are strongly recommended.
