Yet another dry box

The weather started to get wet, and the filaments open in the air too, leaving some stringing in a typical "fine-features-test-print".

Seeing the recent Stacker3D's "F-box" finally pushed me to add this accessory to my printer setup. Their box is cool but use a sort of cartridge for the desiccant.
Polymaker's box is nice but too big, and "just an enclosure" as RichRap said.

So I went to make yet another dry box, and from RichRap concept I kept the idea of the hygrometer sensor, but wanted an analog one to avoid electronic parts and keep things simple.
