Spool Roller

This spool holder works in conjunction with the filament shelf bracket that I designed. It allows for the filament to be printed directly from the PVC shelf. This frees up space and eliminating mass from the printer's frame, if that is where the filament is usually mounted.

Both parts may have to be scaled up by 2540%. Each roller requires printing 2 bearings. The bearings were designed by BoomZilla1, (https://www.thingiverse.com/thing:2746804). I merely scaled up his design so it fit the 1/2" PVC pipe (sch. 40 or sch. 80 both are .840" OD). The length of the roller should accommodate most spools, but can be shortened if desired.
