FolgerTech Prusa i3 2020 Filament Guide

thingiverse

I really appreciate pjvpjv's innovative spool rollers for the 2020, but I still experience issues with filament sliding off the side of very full spools and winding around the 2020 support rail, causing jams. That's why I designed this custom filament guide to direct the filament off the spool from its center. I printed it in ABS plastic and smoothed out the interior with a little acetone, although that step is likely unnecessary. The results are excellent - it works flawlessly. To secure the guide into the stepper motor, you'll need two 30mm M3 bolts. The existing bolts won't be long enough for this purpose.
