SUNLU FilaDryer S2 Filament Dryer
Description
Damp filament can cause stringing, popping and weak prints, and drying it is the fix. The S2 holds one spool on bearings, heats it from all sides up to 70 °C and shows the humidity inside the box, so you can see when the job is done. It doubles as a spool holder while you print.
