Printrbot Gear Head Extruder - Bowden Mount

This is a mod of the Printrbot Gear Head Extruder to allow its use on a bowden tube printer. Very much a WIP.

Update #1 - It works. Printed it in PLA and then ran a 10 hour print using it. It may not hold up long term... I'll probably re-print in a higher temperature material.

Update #2 - Printed for 50+ hours so far, a little creep in the PLA has caused the extrusion rate to change. Still working though. Updated the design with more support.

I don't suppose you have the other side of the part, do you? (The non-Motor side)...I can recreate it, but would rather not.
