I have bougtht several round Temperature and Humidity Meters to put them inside the filament spool holders. I have used one in my 3D printer chamber for temperature and humidity indication. These meeters are tiny and round. I could have them lying on the paver stone near the printer. In that case, position is quite low and watching at them impractical due to awkward viewing angle. I decided to design some kind of stand for this purpose. The result is here.

Humidity & temperature sensors was purchased at Aliexpress Jidi Online Store: https://www.aliexpress.com/item/4000341246649.html?spm=a2g0s.9042311.0.0.32d24c4dL5qlxW

The sensors dimensions are:

• DIA 41mm, height = 16mm max. Nice to know if you want to print one yourself.

This holder is simple, but nice looking (I think) and practical. I have a WiFi Tuya meeter in the printer chamber as well, with its own stand, which will be described in next Thing.
