About This

【Dual-Outlet & Ultra-Smooth Feeding System】 Engineered for versatile "Store-While-Print" workflows. Unlike standard bins, this box features two filament outlets (Top & Side), allowing you to place this filament keeper on the floor, desktop, or rack without bending the tube. The built-in heavy-duty spool holder with dual ball-bearings significantly reduces extruder friction, ensuring consistent tension to prevent tangles or jams.
【End-to-End Sealing & Passive Dehydrator】We don't just seal the box; we seal the entire system. Acts as a highly effective passive dehydrator to protect hygroscopic materials like Nylon, TPU, ASA，PC, and PVA. Alongside the industrial-grade silicone gasket, this kit includes a specialized PTFE Tube Sealing Cap. Simply cap the tube when not printing to prevent moisture backflow and maintain an ultra-dry environment.
【Visualized Rapid Dehumidification: 55% to 20% in 10 Mins】 Witness the efficiency of our airtight system paired with high-performance desiccant packs. In standard testing, humidity levels drop from 55% down to 20% in just 10 minutes, effectively creating a safe storage zone. The built-in precision hygrometer allows you to monitor this fast drying process in real-time. (Note: Keeps filament dry using silica gel, no electricity required).
【Universal Fit & Space-Saving Organizer】 Designed as a compact filament caddy to accommodate 99% of standard 1kg (2.2lbs) spools with diameters up to 205mm. The transparent case allows you to check remaining quantity at a glance without breaking the seal. A vital addition to your 3D printing accessories, fitting perfectly next to Bambu Lab, Ender, or Prusa printers.
【Complete "Pro-User" Accessory Kit & Great Gift Choice】 Ready to use right out of the box. The kit includes the Airtight Box, PTFE Tube, Pneumatic Fittings, a Tube Sealing Cap (for airtight storage), Hygrometer, 2 packs of Color-Changing Desiccant, and a Bonus Pro Tube Cutter. Backed by Fuitnerd's 1-Year Warranty and lifetime technical support with our California-based service. A practical gift choice for friends or colleagues who use 3D printers and need a superior filament storage solution.
