Upgraded spool holder for round hydrometer

This is a spool, round hygrometer, and desiccant holder you can use to turn a cereal box into a dry box for a single spool of filament.

I really like the original model and all addons of the remixed one, but I still had some round hygrometers left over from other projects so I would have to make a change.
