Airtight Filament Box

Since boxes like eSUN filament boxes cost nearly a hundred bucks, just to keep one single filament roll dry and tempered, I designed my own. To make it work, you'll need these add-ons: A hygrometer/thermometer (I used this one: https://www.ebay.de/itm/264347580514) A heat mat (i.e. https://www.ebay.de/itm/Heizmatte-wahlweise-5W-7W-14W-20W-28W-35W-45W-Heizmatten-Terrarium-Heizung/163701295512?var=463192412926) Some rubber glue or rubber bands for the lid's cutout rim Alternatively, some sponge for the lid (instead of silica) Some plexiglass to cover the cutouts on the front Since you can add silica in the holder at the backside of the box, it will keep your filament dry – i.e., for large prints. The head bed will get rid of air moisture while the silica or sponge attract that fluid. You could also replace the filament outlet with a real nozzle, but since the hole is so small and the inside heat is high, it will prevent too much moisture from entering the box. Print time is about three days, depending on your settings.
