The file 'Bearing For Filament Spindle 3D Printer Model' is (stl,bfb) file type, size is 2.2 MB.
This bearing has an outer diameter of 51.5mm and an inner diameter of 8mm, making it perfect for making a resistance-free spindle out of an 8mm bolt, for example the one from the stock Rapman spindle. The outer diameter fits perfectly in reels from orbi-tech.de and the photos seen here are made using their amazing custom PLA mix.
This is also just a fun piece to print as it spins freely with hardly any cleaning up!
