This is a simple model of a stand for a  cheap Hygrometer from aliexpress. I bought some to put on the filament boxes and i wanted to have some way to have it display the room temperature and Humidity.

Some users have reported that the model is a little bit tight. If it is really tough to insert, you can always scrape the hole little bit with a knife or sand paper. The tab recess doesn't goes trough the hole to add tightness also. the idea is to have a solid connection so you can move the hygrometer without rattling or moving.

This Hygrometer should work - link
