Keep Your Filament Dry and Print-Ready Between Uses Moisture is the #1 cause of poor print quality with hygroscopic filaments like PETG, Nylon, TPU, PVA, and ABS. This single-spool filament dry box actively maintains low humidity with a reusable silica gel desiccant, feeds directly to your printer via PTFE tube, and displays real-time humidity and temperature so you know your filament is always in ideal condition. Capacity: 1 standard 1kg spool (fits spools up to 200mm diameter) Humidity Display: Built-in digital hygrometer — real-time humidity and temperature Desiccant: Reusable silica gel desiccant included (rechargeable in oven or microwave) Feed Port: PTFE-lined feed tube port — print directly from dry storage Seal: Airtight lid with silicone gasket Spool Bearing: Smooth-rolling spool support for tangle-free, low-resistance feeding Compatibility: All standard 1kg spools — Bambu Lab, eSUN, Polymaker, Hatchbox, and more Material: Food-grade ABS and PP Essential for anyone printing PETG, Nylon, TPU, or ABS. Pairs well with the Bambu Lab AMS HT for pre-dried engineering filaments.
