Air quality lamp for CO2 metering (MH-Z19, esp32 and neopixel) with honeycombshell

The Senosor became too hot on the first model despite the honeycomb on the lid. For this reason, I also had to design the outer wall with honeycomb. Now there is no heat problem in the housing and the sensor measures the content of CO2 in the air without problems.

I added the "3mf"-file because I still use the infill trick (look at the blog post her) for the top side of the lid. The Prusa Slicer produces a more uniform honeycomb. I used the honeycomb infill with 30%.
