PrintDry Vacuum Sealed Filament Storage Containers (5-pack)

(**Now includes a rechargeable battery powered electric pump for easier and more precise vacuum control!**) The ultimate storage solution to prevent your 3D printing filaments from absorbing moisture! Often a new spool of filament will print very good when first removed from it's air tight package, but print quality can deteriorates after a few weeks/months (or hours/days with Nylon) in storage. Most 3D printing filaments (ABS, PLA, PETG, PETT, TPU, PC and especially Nylon) are hygroscopic materials, which have a strong affinity for moisture. Once removed from their original packaging, these filaments can readily begin to absorb moisture from the air. Even a small amount of moisture in the filament can cause streaks, bubbles, burning, brittleness, increased "stringing", and even a chemical reaction (hydrolysis) when the filament melts, passing through the heated nozzle. When this happens, the filament will make a popping/cracking/hissing sound and the 3D prints will have rough/grai
