I purchased some of the Bambu Lab temperature & humidity sensors (which are great value at just under 3 Euros each) as my wife likes to know these things in random places around the house. I designed this little stand for them and thought someone else may find it useful!

This is very easy to print, it prints in one piece and you just have to push-fit the sensor into the stand after printing. I have used PETG-CF in the profile, but you can change it to any basic plastic and it will work. Enjoy!
