MacPi Pro XL AirMate
thingiverse
A remix of the MacPro from The Craft Dude to get air quality sensors into it: https://www.thingiverse.com/thing:2720091 I did not change the bottom you have either modify the original bottom and add drill holes or screw the small sensor directly into the bottom. The MacPi_Pro_XL_inner_fan_mount_V03c1a.stl is multipurpose, ugly bit you can mount an SDS011 and other sensors to it. I made the Top Fan Mount 2mm thin and used an extension to get a 40x40x20mm fan into it due to the sensors.
