Under-Mounted Filament Spool Rig

A key design goal in my LACK enclosure (see: https://www.thingiverse.com/thing:2613678) was quick and easy removal of the top. Most other designs set the spool on top of the cabinet, meaning you need to unload the filament to get the top off completely. I’ve rigged it to mount below the printer and feed up via a pulley of sorts.
