About this gig
Production-Ready DFM CAD & Mechanical Product Design, For Hardware Startups, Amazon FBA Sellers & Engineers
A great 3D model means little if it cannot be manufactured. I create production-ready DFM CAD design, 3D modeling, mechanical design, and technical drawings built for real manufacturing.
I support Injection Molding, Silicone Product Design, CNC Machining, Sheet Metal, Enclosures, and 3D Printing resolving manufacturability issues before prototyping or tooling.
WHAT I SPECIALIZE IN:
- DFM CAD & Mechanical Product Design
- SolidWorks 3D CAD & Fusion 360 assemblies
- Injection molding: draft angles, wall thickness, ribs, cores & sink prevention
- Silicone product design for molded flexible parts
- CNC machining, sheet metal & product enclosures
- Reverse engineering: STL/mesh to parametric STEP
- 2D technical drawings, tolerances & GD&T
FILES & DELIVERABLES:
- STEP, IGES, STL, DXF, DWG & OBJ
- SolidWorks SLDPRT/SLDASM & Fusion 360 files
- PDF manufacturing drawings & renders
The goal is simple: deliver accurate, factory-ready CAD manufacturers can quote, prototype, and produce.

FAQ
Can you work from a sketch, image, or basic product idea?
Yes. I can develop your concept, sketch, reference image, or existing CAD into a detailed 3D CAD model designed around your intended manufacturing process.
Can you design products specifically for manufacturing?
Yes. I use DFM principles for injection molding, silicone molding, CNC machining, sheet metal, and 3D printing to identify potential manufacturing issues before production.
Can you design silicone products and flexible parts?
Yes. I can design silicone components and products with the geometry, wall thickness, parting considerations, and manufacturing requirements appropriate for molded silicone.
Will I receive the source and manufacturing files?
Yes. Depending on your package, deliverables can include STEP, IGES, STL, DXF, DWG, SolidWorks, Fusion 360, and detailed PDF technical drawings.
What if my project is complex or I’m not sure which package I need?
No problem. Send me your concept, references, dimensions, existing files, and intended manufacturing method. I’ll review the requirements and recommend the appropriate scope before you order.
