Creality Ender 3 Spool Holder/Roller by 6mm BB

thingiverse

I couldn't get a BB of 4.5mm size, so I bought one with a diameter of 6mm. However, there wasn't much I could do with this larger ball bearing. So I modified it. It's a spool holder made from a 6mm BB, and as expected, the 6mm BB acts like a bearing. File: ender3_pilament_mounter_6mm_BB_Bearing.stl This works perfectly when using bearings of 6mm in diameter. Do not fill the inside with BBs. Leave two or three spaces free. File: ender3_pilament_mounter_6mm_BB_Ring.stl It does not use bearings, but it is still usable. Or to lock bearings so they do not shake. You can use it according to your filament spooler's specifications.
