Filament Tube holder for MakerGear M2

thingiverse

When printing flexible filaments, I've noticed that the loose end of the filament tube going into the extruder tends to pull away from the extruder due to the tension created by the tube, and the filament lacks the strength to keep it aligned properly. To address this issue, I designed a tube holder for the extruder end that securely screws onto the open fan hole with an M3 screw.
