Magnetic mount for round LCD thermometer/hygrometer

thingiverse

Here is my holder for the cheap little thermometer/hygrometer available on Amazon (part number B07BLY177S). It's similar to my ugly little holder, but now it has magnets for mounting to steel surfaces. This holder uses 8x3mm magnets which are also available from Amazon (part number B07B3SDRCP). I have a lot of those on hand since I bought them for some other project and they come in a pack of 100. To assemble the thing, just print it out and then press a magnet into each of the holes. For mine, I found that sticking the magnet on the end of a 6mm hex T-wrench helped me push it in as it was a nice tight fit. Just press the magnet so it's flush with the back edge for the best holding power.
