I have had a project on-the-books for far too long... I have a wine-cooler fridge, that had a broken compressor (already removed), so I plan on turning it into an active drying filament storage unit. The problem I have is currently "analysis paralysis", and "feature creep" and no time to CAD model the rod brackets to fit into the existing molded-shelves. Planned features; - Temperature & humidity sensors. - Heating element (3d-printer build-plate). - Active back-channel fan to suck air from internal top of unit down through a plenum to vent in-front of the heating element. In front of that fan intake will be an easily removable desiccant "cage". - Motor + belts to slowly rotate the filament on the rods. - Venting fan at the back-top of the unit to extract moist air - plus a servo-controlled vent closure mechanism (iris, louvre? I don't know anymore...) - External screen and control panel. But lack of time and very rusty electronics knowledge is slowing me down - so, I store my filament in ziploc bags with re-usable mesh desiccant bags - after drying in a dedicated toaster oven.
