We recommended storing filament in a sealed plastic bag or box after each print. 2. If the filament gets damp, you can bake it in an oven with 50°C(122°F) for about an hour to restore its dryness. Friendly Reminder(After Use): Be sure to insert the free end of the filament into the hole to avoid the filament being tangled for next time use.
