Filament Roller

thingiverse

My normal spool holder never fits and especially with a full spool, always jerks. I saw something like this somewhere, but that design looked unstable to me. So this is not my idea. I don't know who's idea it is. -> When I published this thing, I saw that the original is by THUS. <- I used 4 normal skate (fidget spinner) bearings and 4 M8 bolts. The bolts are screwed directly in the pla, so no nut is necessary.
