I remixed and extended the holder from https://www.thingiverse.com/thing:2248787 to put it under a cover of my own design, because I didn't like the drain pipe housing solution from http://luftdaten.info/feinstaubsensor-bauen/

To be able to mount it to a wall etc., I added a GoPro style mount. There are several other constructions for mounting arms etc., see

Both the bottom part and the cover need to be printed with support.

The bottom contains several prepared holes for the power supply cable, use a sharp knife or a drill to cut open what you need.

The DHT22 is mounted into the bottom plate, outward facing.
