About this gig

Hi! I'm a professional 3D CAD specialist with over [7] years of experience in precise modeling for resin casting, silicone molds, and rapid prototyping.


I create high-accuracy 3D CAD models and print-ready STL files optimized for:

  • Resin casting (jewelry, figurines, embeds, art pieces)
  • Silicone mold masters (two-part designs for clean demolding)
  • Prototypes & product development (functional parts, enclosures, mechanical components)


Using Fusion 360, SolidWorks, or Blender, I deliver detailed, manufacturable designs with perfect tolerances, draft angles, parting lines, alignment keys, vents, and printer-friendly geometry (FDM/resin optimized).


What you'll get:

  • Precise 3D CAD model (native files: .f3d, .sldprt, etc.)
  • Export-ready STL files for 3D printing
  • High-res renders for visualization
  • Design optimization for resin flow, minimal supports, easy mold release


Projects I handle:

  • Custom resin jewelry molds (rings, pendants, earrings, charms)
  • Silicone mold masters for soap, candles, chocolate, bath bombs
  • Functional prototypes (mechanical parts, enclosures, test fits)
  • Multi-cavity mold designs for production efficiency
  • 2D to 3D conversion or sketch-based modeling
