Filament Spool Holders: Airsoft BB Bearings Edition
thingiverse
This is a rolling filament spool holder that I designed for my printer. It uses 6mm airsoft bb's as ball bearings. Print each part 4 times to have one working pair of rolling spool holders. Each bearing takes 13 bbs's. Fits standard size 1kg spools. There's a decent amount of clearance at the bottom so if your spool is smaller, it should be ok. Width wise, it is a two part system, so you can adjust that yourself. This was inspired by the T.U.S.H. and adjusted so I could make one using what I had available.
