One twist changes everything on this 3D printed toy #satisfying

Watch how we fixed a broken 3D printed toy mechanism.

Building a face-changing toy is harder than it looks, especially when it keep snapping. I walk through the redesign process from the failed sliding mechanism to a robust vertical locking system that actually stays together.

If you want to see how to troubleshoot fragile parts and improve your 3D printed projects, this build breakdown is for you.
