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:
This holder is simple, but nice looking (I think) and practical.
I have a WiFi Tuya meeter in the printer chamber as well. This stand is here: https://www.thingiverse.com/thing:4879329.
The stand for a squared-shaped meter is here.
