Mechanical LSDs’ function was visualized in a video on YouTube from 3D Printer Academy, which printed a differential in various colors of plastic to show how it works.

[Evan Stanford] found a simpler way, though: a completely mechanical laser show from 3D-printed parts. The first 10 seconds of the video below completely explains how [Evan] accomplished this build.

In most mechanical systems, metal gears that bend are a bad thing. But not so for strain wave gearing, which is designed to take advantage of a metal gear flexing to achieve an action much like pla… ...

Robert has developed a kinetic custom PC case, a project combining woodworking, 3D-printed components, and acrylic materials to create a dynamic and interactive computer case.
