Self-Contained Filament Storage and Print

This is a storage and print solution, to store individual filament spools in their own relatively sealed box. From the time the spool is placed in the box until it runs out, there is no need to take it out and expose it to excess humidity. I ran an experiment with a set up and a couple of silica gel packs, and the hygrometer showed a drop to; and maintained at 60% (from about 75%).

The spool spins on its own spindle (“hub”) and threads through a hollowed out bolt, minimising contact with the
