3D-printed gearboxes are always an interesting ... 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 ...

These large pressure angles can give rise to self-intersecting gear geometry even with a zero clearance. To get a valid model, such gears need a negative ... "over travel") after switching off the ...

However, plastic threads usually have some sort of gradual thread end. For models that will be 3D printed, there is no reason to choose the standard bevel end bolt, so in this library the blunt start ...
