About this gig

Moving from prototype to mass production? I design plastic parts that mold properly, so you avoid expensive tooling changes, sink marks, warping and rejected tool quotes. I create injection-molding-ready CAD with correct draft angles, uniform wall thickness, ribs, bosses, snap fits, living hinges and gate-friendly geometry. I also review existing designs and mark exactly what needs to change before steel is cut.


What you get:

  • Production-ready 3D CAD in STEP format
  • Draft, undercut and wall-thickness analysis
  • Material suggestions (ABS, PC, PP, nylon, TPU) for your use case
  • 2D drawings with key dimensions and tolerances
  • Parting line, ejection and side-action considerations
  • Notes you can share directly with your molder or tooling supplier


Ideal for consumer products, electronics casings, caps, clips and startup hardware heading to volume manufacturing.


Send your concept, current CAD or a prototype photo along with the expected annual volume. Message me before ordering and I'll confirm scope.

Product & Mechanical Design Engineer. I turn ideas into parts that fit, print, machine and mold right the first time. I design PCB enclosures, 3D printable parts, CNC machined components and injection-molded plastic products, with manufacturing built in from day one, not fixed after the fact. What that means for you: Fewer failed prints and rejected quotes Lower machining and tooling costs Clean STEP, STL and 2D drawing files your shop can use immediately Send me a sketch, a board or a broken part. I'll tell you what it takes and get it built. Message me before ordering.
