No Bearing Filament Spool Desktop Spool Roller

No Bearing Filament Spool Desktop Spool Roller

thingiverse

UPDATED: Version 3. It uses #17 Wire Nails 1 inch. The rollers are slightly convex and wider in this design. I also removed some material to try and prevent friction on the side of the spool. I designed this spool roller to be as cheap as possible. Instead of bearings it uses plastic wheels held in place by #17, 1in Wire Nails. Think Cub Scouts and Pinewood Derby cars. I printed mine on an Ender 3 S1 Pro using PolyTerra PLA from Polymaker.
