Polymaker 3D Printing Sealed Filament Storage Box XL, Fits Up to 3kg Spools, PolyDryer XL Printer Holder, Print Without Breaking the Seal, Compatible with 1.75/2.85/3.00mm

Superior Sealing Performance: Polymaker PolyDryer Box XL, 3D Printing Sealed Filament Storage Box Filament Holder, Sealed Storage for Large Filament Spools, features a high-integrity sealing design verified through water leakage, smoke leakage, and long-duration humidity testing. It delivers sealing performance comparable to the standard PolyDryer Box with no degradation despite its larger internal volume. Print Without Breaking the Seal: The integrated filament feeding system lets you print directly from the sealed box. 3D printing filament routes through sealed airlocks, maintaining the sealed environment during the entire print. No more opening your storage every time you start a job. Always Know Your Filament's Humidity: A built-in hygrometer provides real-time humidity readings, and the included color-changing silica gel desiccant (up to 110g) gives you an instant visual check on moisture levels inside the 3D Printing Sealed Filament Storage box. Built for 3kg Spools: Designed for spools up to 3kg (Ø300 × 118mm), 3D Printing Sealed Filament Storage Box XL reduces spool changes and keeps printing workflows smooth - ideal for print farms and heavy users running large-format or long-duration jobs. User-Centered Design: Easier to carry with an integrated handle, easier to load with a design built for heavy spools, and easier to open with a new latch system. 3D Printing Sealed Filament Storage Box XL is built around real user feedback. Part of the Polymaker PolyDryer Ecosystem: Box XL integrates with the PolyDryer Dry Dock via an optional Dock Adapter (sold separately) for active drying capability. Compatible with 1.75mm, 2.85mm and 3.00mm 3d printing filament diameters.
