About this 3D model

**Update: checkout my own alternative design: "Customizable Planetary Gearset (Cycloidical)" http://www.thingiverse.com/thing:488993** ---- This is a slight modification to emmets gear bearing that makes it post assemblable. Advantages: 1) Zero clearance possible 2) Multicolor with single nozzle printer possible 3) Seperate prints -> no travell moves -> better surface quality **edit:** Don't use zero clearance (the *stl's have), increase the tol parameter to at least 0.3mm so the parts can be put together.
