About this gig

Getting a plastic part manufactured is expensive. If you just send a basic 3D model to a factory, they will usually reject it, or worse, you end up paying thousands for a steel mold that doesn't work right.


I am a tooling engineer. I don't just draw 3D shapes. I design the actual molds that factories use, and I run the flow simulations to prove the part will inject properly without warping, air traps, or sink marks.


Here is what I do:


  • Full injection mold CAD (core, cavity, cooling lines, sliders)


  • Moldflow analysis (testing the plastic flow before you pay for tooling)


  • DFM checks (fixing your design so it can actually be molded)


  • Standard CAD modeling and product design


  • Prepping files for CNC machining and 3D printing


  • 2D technical blueprints for the factory


I also design other types of production tooling. If you need molds for metal casting, ceramics, slip casting, or even custom silicone and chocolate molds, I can handle that too.


My job is to make sure your geometry actually works on the factory floor so you don't waste your manufacturing budget on bad tooling.


Send me a message with your 3D file, sketch, or idea before you place an order.

Hi. I'm a mechanical engineer and 3D CAD designer. I create custom models for 3D printing, design plastic injection molds, and fix messy or broken STL files. My main goal is just giving you clean files that are actually ready to be manufactured, without the headache. Send me a message about your idea and we can figure it out.
