silica container for dry filament storage in crate

thingiverse

My solution for filament storageEspecially in winter time when air humidity is high (around 70%) where I live. I had many printing issues as my filament was not dry.I tried several solutions including an active filament dryer. None worked.My working solution is storing filament in airtight boxes with silica gel in containers on the bottom of the crate. As the bottom of the crate is bigger than my printer the container consists of four parts, each with a perforated lid. Humidity in the crate is as low as 2.1%RH. No more printing issues due to wet filament.models in this thing:silica container for dry filament storage in crate.stlslit holes perforated lid silica container for dry filament storage in crate.stlsquare holes perforated lid silica container for dry filament storage in crate.stlYou need 4 containers, each with a lid. 2 as in the models in this thing, 2 mirrored. Mirror the model in the slicer.There are 2 models for the lid. One with slit holes, one with square holes. Choose the lid you like best. Both have the same outside dimensions.The lid is mounted on the container with a flathead M4 screw.other partsThe crate is of type : IRIS Airtight Box 20l. It fits 4 roles of filamentMy advise is to remove the cardboard box as it contains a lot of moisture.The silica gel is available on amazon and in many other on-line stores.I also added humidity sensors in the crate that are linked to my home automation via zigbee, so I can easily monitor humidity in the crate and trigger me when silica gel is to be replaced/regenerated.Tuya ZTH02 fits nicely in the bulge of the crate however looks to not report values lower than 6% RH. Zigbee sensor Tuya WSD500A does report lower values but sticks out a little from the bulge in the crate. As a datanerd I prefer WSD500A bit to be honest values of 6% RH are more than OK for filament storage so ZTH02 fulfils the need for dry filament.
