AirGradient Case

This is a refactory of the official AirGradient case. I decided to rebuild my own due to some flaw (imh) of the original one:

* The PM2 sensor does not fit if it's aligned to the PCB silkmask
* Odd wall mount holes orientation
* Display hole misaligned and too big
* Original snap clips impossible to open once closed!

I'm providing the Fusion 360 project if you want to customized it and the STEP files as well.... and of course the .3mf and .stl files for print.
