Polymaker PolyDryer Filament Storage Box Only (No Dock), Airtight Moisture Proof 3D Printer Spool Container with Hygrometer for 1kg PLA PETG ABS TPU Nylon, Feed & Print Directly Without Breaking Seal

Features

• CONSISTENT FILAMENT PROTECTION - Designed for dependable filament storage, PolyDryer filament storage box helps keep moisture-sensitive filament in a better printing state between uses. By reducing exposure to humid air, it helps lower common moisture-related issues such as stringing, bubbling, clogging, and uneven layer results for more consistent day-to-day printing.
• SEAL + DESICCANT PROTECTION - More than a simple container, this airtight filament storage solution combines sealed enclosure design with desiccant support to help lock out moisture and protect filament between prints. It is built for longer-term storage needs when you want your spool kept in a cleaner, drier condition while waiting for the next job.
• HUMIDITY MONITORING WITH HYGROMETER - Use it as a humidity control filament box and track storage conditions more easily with the built-in hygrometer. The visible humidity reading makes it easier to monitor, judge, and maintain a more suitable environment for your filament, without relying on guesswork alone.
• PRINT WITHOUT BREAKING SEAL - This filament box is designed to support filament feeding while the spool remains stored inside, so you can print without breaking the sealed setup. That means better moisture protection during pauses, overnight storage, and everyday use, while keeping your 3D printer filament storage workflow cleaner and more convenient.
• MULTI-FILAMENT READY & EASY TO USE - Compatible with common filament types including PLA, PETG, ABS, ASA, TPU, PVB, and PA/Nylon, supporting 1.75mm, 2.85mm and 3.00mm up to 1kg spool. The practical design fits neatly into your workspace, making this moisture proof container simple to use. (Note: This includes the storage box only.)
