YAFSH - Yet another filament spool holder.

Yep, it's another one.

I didn't try to look for derivatives, I'm sure there are similar spool holders. I measured as many spools as I could get my hands on, and this taper is carefully chosen to ensure that it fits all those spools. No guarantee that this will fit your spool. Requires 2 608 bearings, designed to be used with M8 or 5/16th inch threaded rod.
