MonoPrice Mini V2 Spool Wheel (2.225ID) holder

Spool Wheel Holder with reinforced arms, drum style spool holder for Tianse 2.225" ID Filament Spool. 2 10mm bearings with 26mm OD.

I didn't like the arms with holes in them of the original design and/or just setting the spool on a rod. This rolls like butter.

- added a 54.5mm hub for hatchbox filament
