I use a bunch of these Thermo-Hygrometers from “TFA Dostmann” around the flat to keep an eye on the humidity. The originally came with a little stand you could clip to the backside of the device but they all broke or got lost so I designed my own.

It prints quickly without any supports and keeps the device tilted backwards by 10 degrees to make the display more readable. The slots on the back are kept free to ensure good circulation around the sensor on the inside.

Happy printing :)
