Filament stand. Pretty plain and simple.

Big enough to hold all of the different 1kg spools I have. It is untested for spools bigger than 1kg.

Print 2 and hook them up back to back.

I added a slightly shorter version that fits on my FFP Clone. Still fits 1k rolls.

New Rod with bearings for smoother rolling.

Added a 4th bearing for a more even support of the spool.
