Keep opened 3D printing filament organized, protected, and ready for your next print with the SHOWPIN Filament Vacuum Storage Kit. Moisture is one of the most common problems for opened filament rolls. Once filament absorbs moisture from the air, it may lead to stringing, bubbles, poor layer adhesion, brittle material, rough surfaces, and inconsistent printing results. This kit is designed to help users store dried filament more efficiently by combining vacuum storage bags, an electric pump, and desiccant packs into one simple storage system. The 60Kpa electric pump makes the sealing process easier than traditional manual hand pumps. Place the filament roll into the bag, add a desiccant pack, close the zipper with the sealing clip, align the pump over the valve, and remove excess air. This makes it easier to manage multiple opened rolls in a print room, workshop, school, maker space, or home 3D printing setup. Each bag is designed for repeated use, making it practical for users who frequently switch between colors and materials. The black side helps reduce light exposure during storage, while the visible side helps you identify the filament without opening the bag. Use the included marker to label material type, color, drying date, or opening date for easier spool management. For better sealing performance, make sure the zipper is fully closed, the valve is flat, and the pump is centered firmly over the valve before vacuuming. Pressing around the valve after removing air can also help improve the seal. Proper use is important for maintaining a better vacuum storage result over time. The 12.6 x 13.4 in / 32 x 34 cm bags fit most standard 0.5 kg, 0.75 kg, and 1 kg filament rolls, including 1.75 mm, 2.85 mm, and 3 mm materials. Suitable for PLA, PETG, ABS, TPU, nylon, PC, PA, ASA, PVA, HIPS, and other common 3D printing materials. Package includes: 20 filament vacuum storage bags, 1 electric vacuum pump, 20 silica gel desiccant packs, 4 sealing clips, 1 dual-tip marker, and 1 English user manual.
