Duck CheckedMoisture routine
Does this spool need a bag, a dry box, or drying?
Those are three different jobs. A sealed container slows new moisture. A dry feed path protects sensitive filament during a print. Drying tries to remove moisture already absorbed.
Do not borrow another material's temperature
The useful drying number belongs to the exact material, and the spool itself must tolerate it. A household oven that swings around the set point can soften filament before anybody notices.
