Gig Summary
About this gig
I design 3d models for 3d printing and also I fix broken STL, STEP, OBJ, and 3MF files and repair mesh errors so your 3D model prints without failures.
Certified mechanical design engineer (SolidWorks) with real print-farm experience. I repair non-manifold geometry, fix flipped normals, thin walls, and holes then hollow, split, and scale your file for flawless FDM or resin printing.
WHAT I FIX:
- Non-manifold & non-watertight mesh errors
- Broken/corrupted STL, STEP, OBJ, 3MF files
- Flipped normals, holes, thin walls, defects
- Splitting large models for Bambu Lab/Creality/Prusa
- Hollowing + wall thickness correction
- File size reduction, detail preserved
- Reference images/sketches to printable 3D models
WHY ME:
- Mechanical engineering background I understand tolerances and manufacturability, not just mesh math
- Real experience supplying US-based print farms
- Free file diagnosis before you order
- Unlimited revisions until print-ready
FORMATS: STL, STEP, OBJ, 3MF, FBX
Send your file for a free diagnosis before ordering.
