About this gig

Need a plastic part designed correctly the first time without expensive mold redesigns?


I design injection mold parts in Fusion 360 with design for manufacturability (DFM) principles built in correct wall thickness, draft angles, parting lines, and gate locations from the start.


I work with Amazon FBA sellers, product manufacturers, and industrial clients who need clean, production ready STEP files their factory can use immediately.


What you'll get includes:

  • Plastic enclosures and housing shells
  • Consumer product injection mold components
  • Multi part assemblies with snap fits and interlocks
  • Packaging components and cosmetic shells
  • Functional plastic parts for industrial applications
  • Injection mold ready 3D CAD model in Fusion 360
  • STEP and IGES files
  • STL file for prototype verification
  • Draft angles, wall thickness, and parting line considered
  • Native Fusion 360 file included (Standard & Premium)
  • Revisions until the design is right


Perfect For:

  • Amazon FBA sellers developing private label products
  • Startups needing a DFM ready file before tooling
  • Engineers requiring a component redesign for injection molding
