Kuro's Compact Bowden Geared Extruder

Kuro's Compact Bowden Geared Extruder UPDATE: gears should fit each other with less slop now. Designed to fit a Rostock Mini, this design can be used in other printer adjusting the support, that is fixed on two of the extruder motor bolt holes. It uses a MK7 drive gear and 625zz bearings. The only thing I didn't really like on this extruder is the use of a 3/16" nut to fix the PTFE. It's troublesome to assemble and I really prefer using the press fits. It's recommended to fit the 3/16" nut and then fixing the PTFE in the extruder the first thing, or you will have some bad time fixing it after assembly of the extruder.
