I created this cover to protect the Rosahl RS1 dehumidifier that I'm using for my AllSky Camera project. I use a small ePTFE membrane between the Rosahl and this cover to protect it from rain and dust. The company that sells the Rosahl dehumidifiers makes and sells covers for the larger models, but not the RS1, so I decided to design and print my own. Hope it'll be useful to others too.
