Wall Mounted Filament Roller

A simple wall-mounted filament spool holder/roller. Mount your filament spool onto the wall instead of on your printer where it increases vibration and top-heaviness, reducing print quality. Full cylinder shape for extra strength.Spool holding section is about 70mm wide, which fits almost all 1kg spools.No supports needed. I printed in PETG-CF for extra strength and rigidity, but PLA should work just fine. Recommend 3-5 wall loops and min. 25% infill.Four screw holes (3.75mm diameter) fit M4 or slightly smaller screws.*Make sure to use drywall anchors if screwing directly into drywall.*Tip: Wrap scotch tape around each end of the roller where the spool rolls to make for smoother rotation!Let me know if you think of any improvements!
