Flexible filament guide (w/ PTFE Bowden Tubing) for MP Select Mini w/Anycubic Mk8 extruder modified w/OEM gear & flat bearing

thingiverse

This remix resolves several problems I encountered with the original:\r\n* The Anycubic Mk8 extruder has a set screw holding the spring that obstructed the fit of the back of the guide.\r\n* The arrow-shaped guide section hindered the idler's spinning motion and collided with the set screw on the extruder drive gear. I shortened the length of the "arrow".\r\n* Flexible materials still accumulated in the gap between the guide and the beginning of the Bowden tube (inside the brass base). I fixed this issue by enlarging the guide hole to 4.1mm and inserting a small section of PTFE Bowden Tubing (OD 4.0mm) that connects the Bowden coupler all the way to the idler/extruder gear.\r\nThanks DtEW for providing the guide I used to print the tires from: https://www.thingiverse.com/thing:1193309
