Remote Driven Extruder, not a bowden

thingiverse

This experimental remote-controlled extruder aims to deliver Bowden speed and traditional accuracy; however, it remains untested. Assembled correctly in Inventor assembly, the creator shares the design for others to try until they test it themselves. The motor mount and idler belt are lowered for better clearance, while most parts need rotation to bed level. All ipt files for Inventor are included, with adaptability for other shafts requiring a changed little gear insert and coupling. The 608 bearing's internal diameter limits the shaft size, but the big gear file is not uploaded. New STLs corrected from cm to mm have been added. Inspired by http://garyhodgson.com/reprap/wp-content/uploads/2012/01/Prusa-Mendel-Off-Carriage-Extruder-PoC-MattRobertsCompactExtruder.png, this design requires a 608 skate bearing and Vex Robotics square shaft (12 inches), along with printed parts and two couplings. The insert in the bearing on the x-end holds the square shaft, and alignment can be fine-tuned using slotted holes. It uses Greg's X-carriage design (http://www.thingiverse.com/thing:9869) for reference.
