quick, threaded, self-centering, ball-bearing spool mount
thingiverse
Change spools super fast and easy, without tools! Simple, handy, and 100% printable. works for spools with center hole 22-58mm, and around 50-100mm wide. SKF 608 ball bearings fit on each side (8x22x7mm), but it will work good without them, too. I recommend using PLA, ABS may just not have enough layer adhesion to work on these Parts. Instructions My first one printed very good with 0.2mm layers, 0.4mm nozzle. Set outer perimeters NOT to be printed first, and print with supports for the first ~10mm. Again, I recommend using PLA for this part.
