Fully 3D printable filament spool holder with ball bearings

thingiverse

This is a fully printable filament spool holder with ball bearings, which makes the rotation of the spool better. The full system is in 4 pieces: - 1x filamentholder - 1x filamentholder screw - 2x 608 bearings The filamentholder fits right into the hole that the original filamentholder uses, and the filamentholder screw can be screwed on to keep it there. The screw might be thight. The filamentholder doesn't require much infill (i did 20%). But the screw is better with 30%+. The screw might be so tight that you need to print it in down to 95% scale. It uses 3D printed bearings that i borrowed from guppyk, but it should also work with regular iron bearings. https://www.thingiverse.com/thing:4821342 I have included both the Min and Max bearings. Min have narrower gaps between walls and needs more attention. When printing the bearings: - Fill gaps between walls (off) - Thinner profiles The bearings probably need some squeezing and rolling.
