Four part 3D printed mold

thingiverse

Last week's success with the two-part mold has brought significant progress. I'm drafting more in the mold, seeing less pinching occur, and upgrading to a bigger pour spout. With Pam serving as mold release, everything is working perfectly. I've included the Rhino file for your reference, and now it's time to move on to writing software that can automatically draw parting lines on complex objects. That sounds like an exciting next step.
