Bearing for 123-3d spool

Bearing Mount for Ender 3 Filament Spool Holder ============================================= This design fills the gap between standard Ender 3 filament spool holders and 123-3D brand filament rolls. Printing it in nylon is a smart choice, as it has a lower coefficient of friction. However, I didn't have nylon available at the time, so I made it out of beige PLA. The model uses exact measurements, but you may want to upscale it slightly for tolerance purposes. To assemble the bearing mount, attach two bearing covers to the sides. This will prevent the bearing from falling apart. You'll need to print two of these covers and attach them to the side mounts.
