Keep your filament dry with the Polymaker PolyBox. This is a filament storage box which uses silica gel desiccant satchets to maintain your filament at its ideal printing environment built in with a Thermo-Hydrometer to precisely monitor the humidity and temperature levels inside. The PolyBox maintains a below 15% moisture level to prevent absorption into the filament.
It can store two 1kg spools or one 3kg spool in both 1.75mm and 2.85mm diameter.
