About this service

Need a custom part designed or prepared for 3D printing? I can help turn your idea into a functional, production-ready CAD model.

My services include:
• Custom 3D CAD modeling
• Product and prototype design
• Design optimization for FDM 3D printing
• STL file creation and modification
• Reverse engineering from sketches, photos, or dimensions
• Replacement parts and custom brackets
• Jig and fixture design
• Manufacturing and assembly considerations
• Prototype test printing (available upon request)

If needed, I can print and test prototypes on my own 3D printer before delivering the final files, helping identify fitment or design issues early. Final deliverables can include STEP, STL, OBJ, DXF, or other common CAD formats.

My goal is to provide accurate designs, clear communication, and practical engineering solutions that are ready for manufacturing or 3D printing.
