Air Tight Spool Holder w/ Hygrometer

prusaprinters

Keep your filament dry with this simple spool holder designed to fit up to an 8" spool in a 4L air tight cereal box. There is a cutout in the front for a mini hygrometer to track the humidity and temperature of your filament. There is space behind and underneath the spool to fit your preferred desiccant. I personally use 100g reusable packs slotted behind the spool.

There was some minor sag under the overhang, but this is covered by the hygrometer. You can print up to three at once on a 256x256 bed.4 Pack - 4L Air Tight Container6 Pack - Mini Hygrometer10 Pack - 100g Reusable Desiccant Packs
