This is a planetary gear box system that was designed to serve as a medium mug coaster. A little extra, but just in the right way. The entire system is in inches, so please import accordingly. If it is imported in a different size, or if the nozzle size is greater than .4mm, I cannot say that the gears will mesh well with each other. I did include a small offset from all teeth in the parts to account for normal nozzle overflow.

This part uses metric hardware for connection: 4 x M3x10 button head cap screws and 4x M3 nuts. This use of hardware over pins allows for the parts to be fully joined together, but also allows the potential for disassembly and cleaning.
