Hygrometer Wall Mount

This is a magnetic wall mount for a relatively low cost hygrometer / thermometer available from Aliexpress etc.
The hygrometer has a couple of magnets mounted on its back and this design couples those magnets with 2 more that are secure inside the mounting bracket.
In my case I used 7 diameter x 10 long neodymium magnets but it would be an easy modification to the STEP file should you already have different size magnets.

The hygrometer is easily hooked and unhooked from the mount which is ideal if you want to monitor conditions in more than location. You just need a mount in each location.
