Planetary Gear System

This planetary gear system is for educational purposes. It helped me physically see the 3 ways power transmission occurs, by locking any gear. The shaft is a standard hexagonal pencil, and needs 2 or more pencil collars to lock the shaft's DOF in the assembly. The Annulus and Annulus Mount should be glued together, and the Planet Carrier and Pins should be hammered down. No parts need scale down as backlash is enough to compensate for possible thermal expansion or shrinking when done printing
