Gemstock Filament Spool Holder

I needed a place on my Gemstock to put my filament spool during printing, having to use a separate filament holder that is loose on the table was never something I was a big fan of.

This mounts onto the extrusion of the Gemstock using M3 T-nuts and the filament spool bar attaches onto the base using M3 bolts, use quite long ones (max 35mm) otherwise it will fall off under the weight of the filament spool.
