Filament Spool Bearing Spacer
thingiverse
The Original Bearing Filament Spool Support has been greatly improved by allowing the filament spool to turn freely. Unfortunately, I frequently over tighten the outer nut, forcing the Spool End Cover into the outer bearing assembly which causes the assembly to shift inwardly and results in excessive drag due to friction between the Spool End Cover and the spool. My flanged spacer has been installed between the two bearing assemblies, preventing the outside Spool End Cover from rubbing against the filament spool. Designed specifically for my used filament spool size (thickness), the spacer measures 33.5mm in inside diameter and 36mm in length. Prints as a vertical cylinder without support.
