Filament Spool Adapters with Skate Bearing

3d printed adapters for filament spools. a standard skateboard bearing fits in the adapters so they can roll very smoothly and not put strain on the filament while printing. The arms are for the Prusa I3 printer. The bearing is a standard skate bearing 7mm deep, 22mm wide and 8mm inner diameter. I use a screwdriver with a 8mm shaft to support the spool between the arms. Sizes included 32mm, 50mm, 51.5mm, 54.5mm. I also included a spool adapter that can fit various sizes.
