Minimalistic extruder for CTC prusa i3
thingiverse
Extruder designed for my CTC Prusa I3 Pro B kit to replace the stock extruder. The extruder employs a ball bearing and a spring or M3 bolt to tighten the components in place. The bearing is secured by any M4 bolt/screw. Bearing: U604ZZ U-groove (any bearing with 4mm ID and max 14 mm OD will work) Spring: 10mm spring with inside dimension of 8mm (the one used is 25mm long) This extruder can be printed without support. This extruder is based on the minimalistic MK7 replacement from Whosawhatsis.
