[WIP] CerbrisReborn 1.75mm bowden extruder

youmagine

Closely threads the filament after the hobbed gear.To secure the bowden coupler, enlarge the mounting hole to 9mm, then soak with acetone. As the plastic softens up, carefully screw in the coupler until it's flush.The lever's screw should jam in the stepper's thread when tightened against the M3 screw that holds the motor together from the opposite side. Apply thread lock for optimal results.Variations with different bowden mounts, spring options and filament diameters are on the way!Based on / inspired by WhosaWhatsis' "Minimalistic MK7 replacement" http://www.thingiverse.com/thing:15718
