Self-Contained Filament Storage and Print

thingiverse

This is a storage and drying solution for individual filament spools in sealed containers that protect against humidity. When storing filament spool in one of these units until it runs out, exposure to excess moisture is eliminated. To test this system, I ran an experiment using two silica gel packs, and the results showed a consistent reading on the hygrometer of 60%, from an initial level of about 75%. The filament spins on its own spindle ("hub") through a hollowed bolt, reducing air contact with the surrounding area. Although not perfectly sealed, I am confident it offers better protection than removing the spool and exposing it to the ambient environment for hours. In past times, humidity did not seem relevant, but having witnessed that new, stored filament exhibits a smoother flow with less irregularity compared to exposed filaments in 70%+ relative humidity environments. This observation has led me to believe in the importance of low humidity conditions during storage.
