Spool Filament Tidy Clip

It never works poking the filament through the holes in the spool, and I was getting fed up taping the filament back to the spool, so these clips slide around the rim as needed and keep the filament tidy.

Designed specifically for the ColorFabb spools, but seems to work with monsterfill spools too.

Updated: Shorter clip (quicker to print) slightly tweaked design, and video added showing how to attach.
