No Bearing Filament Spool Desktop Spool Roller
Description
I designed this spool roller to be as cheap as possible. Instead of bearings it uses plastic wheels held in place by #16 1-1/4 Wire Nails. Think Cub Scouts and Pinewood Derby cars. I printed mine on an Ender 3 S1 Pro using PolyTerra PLA from Polymaker.
