A holder for those of us that keep their spools in cupboards upright and don't want them to roll out.
I remixed this from Coex 3D's model due to them falling over and being hard to put the spools on driving me nuts. Connecting the tracks makes it much more usable, it just limits the spools it holds.
This spool holder an eSUN cardboard 1kg spool perfectly. It's 60mm from track to track, so if that's the wideness of your spool you're on the money.
It's a remix from thingiverse.
