3D-printed gearboxes are always an interesting design challenge, especially if you want to make them compact. ZeroBacklash created a little strain wave gearbox (harmonic drive) for when you want to trade speed for torque on NEMA 17 stepper motors. Strain wave gears work by deforming a stationary flexible spline into an ellipse […]
