ender 3 pro filament roller

low friction filament spool holder to replace the stock piece for any filament with a 30mm (40mm to fit over the shoulder) center hole.

uses 608 skateboard bearings. You will also need an m8x1.25 threaded rod, 150mm long, and a couple of m8x1.25 nylock nuts.

I printed this without support, but the bottom facing bearing pocket was a little hairy. Worked fine but you may want to add support.
