A simple mounting bracket / stand for the classic Amazon hygrometer often used im AMS.

You can put the hygrometer standing up without rolling around or hanging from a top or side surface.

Easily fixable and removable using a piece of tape for extra stability if needed. It can also be wedged between shelves and glued or screwed to pretty much anything, depending on the needs.

The bracket is not visible when looking straight on the hygrometer.

Multiple holes all around to place the standing- / hanging-plate whereever you might need it.
