Filament Spool Adapter (.750" bearing)
thingiverse
This is a Filament Spool Adapter with an inset for a 3/4" metal sleeve bearing. For spools with 50mm to 54mm openings.Print TWO.I found the metal sleeve bearing in the parts drawers at my local Home Depot along with a steel rod to really reduce friction.If you want these to stay together without a frame holding them, use the screw holes. The threaded side is UNDERSIZED so you can drill it to the diameter you need for your screws.If the bearings are hard to install, you can sand the hole a little -OR- warm the print up and shove the bearing into the warmed expanded plastic.If the bearing are loose, wrap tape around them.
