Features 2-in-1 Design: Use it as a filament dryer and a stackable storage box. Space-Efficient: Stack multiple storage boxes (up to 3) for enhanced space utilization. Rapid Heating: Reaches 70°C in just 15 minutes, drying filaments efficiently. Adjustable temperature 35-70°C to suit different filament types. Strong Sealing: Silicone seals on both ends ensure excellent insulation and maintain low humidity (average 25% at 50% ambient humidity). Large Capacity: Fits spools from 0.25kg to 3kg, and up to two 1kg spools. Supports spools up to 250mm in diameter and 153mm in width. Universal Compatibility: Works with both 1.75mm and 2.85mm filament diameters. Works with both plastic and paper spool filaments. User-Friendly: Features an integrated carrying handle, and six different filament outlet holes. Built-in Hygrometer: Real-time observation of internal humidity changes Triple Safety Design: Foolproof heating with 200W PTC fan heating, secondary temperature protection switch, and software intelligent temperature control.
