Hey there!

 

I just got some ESP32 board and DHT22 sensor to follow the temperature and humidity. I wanted to install one in the bathroom but as there is a lot of condensation I was afraid for the board. So, I just made this case!

 

It consists of 4 parts : The body, the lid and 2 TPU parts used for watertightness. 

I used PETG for the body and lid and TPU for the seals. 

 

I uploaded my print profiles for the Centauri Carbon and Neptune 4 Pro.

 

The ESP32 is then connected to my Home Assistant running on my Raspberry Pi 5. I can follow the data on it directly as you can see on the screenshots. 

 

You will need some screws to close everything. You will find all details in the bill of materials. 

No nuts or thread inserts needed: you can screw directly into the plastic.
