But drying desiccant is far easier because it withstands boiling temperatures ( 212°f - 100°c) and dries faster. | ||

+ | > Personally, I keep each of my open filaments on a stand inside a separate zip-lock bag with color changing desiccant. I put a small hole in the bottom of the bag and feed the filament out the hole so it never leaves the bag, even while printing. I just put a small piece of tape over the hole if I switch filaments. Once a bag has been taped once, I put a hole in the tape use the spool the 2nd time. If I need to re-seal it, the 2nd piece of tape peels of the 1st piece very easily and so the 2nd piece can be used to re-seal the bag many times. In fact it might last several spools before looing it's stick. | ||

+ | - No need for fancy vacuum bag storage: any smallish air-tight container will do! | ||
