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

thingiverse

This remix fixes a few issues I ran into with the original: * The Anycubic Mk8 extruder has a set screw holding the spring that interfered with the fit of the back of the guide. * The arrow shaped guide section prevented the idler from spinning and ran into the set screw on the extruder drive gear. I reduced the length of the "arrow". * Flexible materials would still bunch up in the gap between the guide and the start of the bowden tube (inside the brass base). I fixed this issue by making the guide hole 4.1mm and slid in a small length of PTFE Bowden Tubing (OD 4.0mm) that joins the bowden coupler all the way to the idler/extruder gear. Thanks DtEW for the guide I used it to print the tires for: https://www.thingiverse.com/thing:1193309
