round humidity meter holder

So I bought round temparature humidity meters (hygrometer) because I thought the would be handier then the square ones. I was wrong, buy the square ones :)

These things are awesome to measure the humidity inside your filament storage box though. This simple print will allow you to mount the round meters with minimal effort. Just a few m3x8mm and a few m3 nuts. The picture should explain the rest I think.

Print instructions

I printer this without supports, "nut side down". It's not pretty but good enough.
