Spool holder for Anet A8

thingiverse

I needed a spool holder for my Anet A8 printer that's easy to use, with spools mounting directly to the printer. This design was born out of necessity. Big bearings might be overkill, but I had them on hand and decided to build around them anyway. Now that I've used it, I realize an empty spool tends to slip on the drum due to subpar bearings. I'm convinced it'll work just fine without bearings altogether. The bearings have a 25mm inner diameter and a 47mm outer diameter.
