Testing a parametric threaded cutter, from SCAD-style CAD to real print

We’ve been experimenting with parametric cutters for adding functional joints to 3D models.

This one is a threaded connector cutter. The idea is to keep the control surface small, with only a few key parameters like radius, depth, pitch, and clearance, then use it to generate printable screw-fit geometry.

Follow up: we’re adding threaded joints so models can screw together

Quick follow up on our cutter tools, we’re turning threaded joints into something you can control with just 4 parameters instead of a long list, generated from code and ready to print as screw fit parts, still tuning it so curious if this feels like the right level of control and what you’d change.

We’ve been improving on a small set of cutters that add joints directly into models, so they can actually move after printing./ Right now we have 5 types:

  • hinge style joints
  • snap fit
  • dovetail
  • slot interlock
  • flexible link style

The goal is simple: take any mesh → split it → add joints → make it printable and usable. Still early, but it’s already working on toys and simple mechanical parts.

Curious what people think, what kind of joints or use cases would you want to see?
