A silica gel desiccant box for dry filament storage. A LCD hygrometer acts as a lid. Designed to fit inside 50 mm spool holes and has a total height of 72.5 mm to match the pictured food container.

The hexagonal shape allows for better airflow and improves desiccant effectiveness (thanks to remix source https://www.thingiverse.com/thing:2717500 for the idea).
