I am keeping my filament in a mostly air tight container on the floor. This angles the hygrometer at 40 degrees to make the screen readable while sitting nearby.

The hygrometer is 43 x 43 x 11.5mm.
This particular model was $9 for a 2 pack but no longer sold through the Amazon page I used. Likely just sold under a new name.

I printed at 8% 3D Honeycomb infill. No need for strength, mostly just how well your printer handles bridging.

This is an overkill for what it is but I had an hour to kill so this is what I made. Enjoy.
