Bowden tube feeder with filament release mechanism - 3mm version

thingiverse

In an update, I adjusted the top plate design to accommodate a 8mm Bearing without touching surrounding walls. If you printed the previous version, use a dremel or knife to modify it. The redesigned bowden mechanism is now compatible with 3mm filament and features several other modifications to suit my setup, including using an M8 ball bearing, a hobbed bolt, and a Nema14 stepper motor with gearbox. Assemble the parts following satoer's video instructions, but note that an 8mm pipe or rod now holds the larger bearing instead of a screw. To install the top plate, cut two supports for the bearing to fit in place. Share your experience if you make this modification!
