3Dator Bowden Extruder MK8 gear (M6 fitting)
thingiverse
My remix of the great Bowden Extruder is a game-changer. Check out my M10 Fitting remix too, if you're looking to get creative with your lathe at http://www.thingiverse.com/thing:2027378. I've also got all my mounts for every version of the extruder right here: http://www.thingiverse.com/thing:2027391. Here's what I changed: I completely revamped it for MK8 gear, added an inspection hole for the gear (visible in the second image), and swapped out square M3 nuts for classic M3 nuts. For version 2: I switched to PC4-M6 instead of PC4-M5 for a longer lifespan. I've also got plans to use PC4-R1/8 in the future. I reinforced the mount for the PC4 connector, optimized the shapes slightly, and added a new holder. You'll need one DIN557 M6 square nut for the fitting mount and 608ZZ and MR105ZZ bearings for the original adapter part. For build materials or building guides, refer to the original extruder. I'm currently testing this version, but I haven't tried it with flex yet. I hope it's still capable of printing flex.
