thingiverse

Want to keep your filament dry? This handy box will dry your filament completely. Simply place the spool inside the box and seal it within a plastic bag. Note that this dryer is designed specifically for Geentech spools, but you may need to adjust its size to fit other brands of filament. To use the dryer effectively, you'll need silica gel and some breathable cloth material with a thickness of about 1mm. For maximum adhesion, consider applying adhesive tape.
