Filament Dryer

A 3D filament dry box is a box with heaters that can dry filament and evaporate moisture. It is usually with a temp sensor and a moisture sensor in it. You can achieve better 3D printing results by drying the filament in a filament dryer before printing. The 3D filament feeds through the hole in the dry box directly into the printer nozzle.
