Dry Box

The filament dryer is composed of two printed parts, a hygrometer from AliExpress, a piece of 2 mm thick plexiglass, Z809 bearings, and 8 mm diameter rods. I shaped the plexiglass using a heat gun and wooden boards to prevent overheating in areas where it could be undesirable (a diagram of the plexiglass is available in the images). The rear part of the plexiglass is secured with electrical tape. All parts are firmly connected, and silica gel is poured into the dryer.
