Filement Spool Bearing/ Reel Centre

thingiverse

I'm fed up with my spools flopping around on its unsuitably sized holder, so I decided to build a neat bearing that fits most of my 1Kg spools. Its dimensions are designed specifically for spools with a 57mm centre hole and a shaft diameter of 32.5mm - perfect for my Creality machine. This new bearing works flawlessly, providing just the right amount of tension to prevent the spool from 'free wheeling' without inhibiting filament dispensing.
