Generic Spool Holder

This filament-spool holder was designed to hold my 1kg spools of filament from Inland, but it should work with most other spools.

I plan on updating this with an attachment for a tube for the filament to run straight from the spool to the 3D printer, so I will no longer need to unmount my spool from the holder and remount it to the back of my 3D printer.
