Spool Holder With Bearings

Add-on spool holder sleeve with MR2437 ball bearings.

Cardboard filament spools seem to me to have a lot of friction sliding on the Prusa spool holder peg. I just happened to have some bearings that fit over the Prusa Mk4 spool peg, so I designed a sleeve to accommodate the bearings and provide a smooth roller for filament spools.

Bearing Model: MR2437 Dimensions: 24mm(ID.) x 37mm(OD.) x 7mm(T.)

There is also a model included for a simple tool to stick into the hex holes of the roller in order to be able to turn and lock the Prusa filament peg back into it's holding arm.
