They don’t exist. Yet this is what [3DprintedLife] needed for a robotic camera arm, so he developed a custom 3D printed high torque strain wave gearbox to be powered by a cheap NEMA23 stepper motor.

If you have access to a 3D printer, there's almost no limit to the ways you can make your office space better without spending too much cash ...

This time I've balanced the drive by using two cycloidal discs 180' out of phase with each other. I've also made the cam shaft much thicker and robust by screwing an M4 bolt through the middle of it.

The rest is mostly 3D printed, so with the right design, you can whip up a wave drive to suit whatever packaging requirements you might have.

Gridfinity is a modular, grid-based storage and organization system that’s optimized for 3D printing and rapid customization.

Lol, indeed. The 3D-printed bracket clamps onto the front screen of the Steam Deck, like a gigantic version of those phone mounts for a console controller.
