Poor Man's Filament Dryer

Turn a 4L Cereal container into an effective filament dryer on the cheap. Simply add desiccant to the holder, screw on the lid, insert the fan, and put it in the hub of the spool of filament. If it doesn't fit in the hub, put it between the sides of the spool. It is amazing how quickly this removes moisture from the air inside the container, consequently, drier air allows the filament to release its stored moisture.
