Differential gearbox for educational purposes. The original gearbox was designed by Thangs user "3D Designer". This is a modified version (remix with permition), so it can be 3D printed too, not only used in animation. Most of the objects needs support for 3D printing. The ring has two versions, one needs supports, the second don't needs supports, but your printer must be able to 3D print 45mm bridges and sacrifice layer has to be removed to get the hole (with knife or similar).
