Easy Prusa spool bearing mount

thingiverse

Wanted an easy bearing mount for my Prusa Mk2s. Spotted that the factory spool holder had a hole on the side opposite the pegs, and thought, why not utilize it. This works perfectly well on spools that have the same diameter inner radius on both sides. Unfortunately, some spools defy logic with ~50mm holes on one side, but ~80mm holes on the other. In such cases, you'll need to print a spacer. This design employs two standard 608 bearings.
