SpoolBox Polydryer

The SpoolBox Polydryer is a premium dry box that integrates the Polydryer as its dryer unit, enclosed in a two-shell housing designed to hold two filament spools.
Why this product?
It was created as an alternative to traditional silica-gel dry boxes, eliminating the hassle of constantly replacing desiccant packs. Instead, the Polydryer ensures consistent drying performance without maintenance.
Note: The previous model is not compatible with this version. Dimensions had to be slightly adjusted to accommodate the Polydryer. This model I mean: https://buymeacoffee.com/cc3dprojects/e/409228
