Starwasher extruder

thingiverse

Update: Added files for 3mm filament. Made a slot in the rotating piece, which greatly improves filament feed. Created an adjuster using a 3mm screw and a small washer in the slot to keep the filament pressed against the o-ring and between the washers. Note: The star washers have two sides - a sharp side and a smoother side. Ensure the smooth side of both washers faces the filament, as the sharp side can damage it and cause binding in the tube. The filament should exit the feeder without damage, only with small dimples. When the hot end reaches temperature, turn off the extruder motor, turn the knob, and the plastic should flow out with minimal resistance. If turning is difficult, there's a problem somewhere in the hot end. More modifications are in progress.
