### Effective Moisture Protection This sealed filament dry box with upgraded molecular sieve desiccant and drying agent creates a low humidity environment. It effectively prevents PLA PETG TPU and nylon filament from absorbing moisture which can cause printing failures and poor surface quality. ### Dual Placement Design The dry box supports both top mount and bottom mount installation. This flexible design allows you to position the filament box above or below your printer based on your workspace and printer configuration. ### Smooth Filament Feeding The box includes metal bearings and a PTFE guide tube to ensure low friction filament delivery. The metal axle holds the spool securely while allowing it to rotate freely for consistent feeding without tangling. ### Real Time Monitoring The built-in temperature and humidity meter lets you check the internal environment at a glance. You can ensure your filament stays in optimal condition without opening the box and exposing it to outside air. ### Complete Accessory Kit This dry box comes with everything you need. Package includes dry box body ×1, desiccant ×2, silicone plugs ×2, metal axle ×2, metal bearings ×4, PTFE guide tube ×1, hygrometer ×1, ABS hanger ×1, and nozzle plugs ×2.
