AirGradient DIY sensor case with upgraded sliding LCD cover for CO2 PM2.5 AQI sensor

I took the design shared by forum user ‘ttielemans’ found here and added a 50 degree dovetail sliding LCD cover. That LCD is quite bright if you're using it in a bedroom and trying to sleep or if you just don't want to see it all the time, etc. There is a 12mm long slit in the cover meant to cut and glue in a section of 1.75mm filament to serve as both a fingernail grab and to lock the door in from falling out the rear drop in slot. The dovetail is designed with 0.15mm clearances.

I also added magnet mounting holes on the back panel for 8x3mm magnets in case you need to place it somewhere…magnetic. These holes are designed with 0.2mm clearance. 
 

And I modded the front blank cover to include corner hold brackets for the AirGradient ‘traffic light’ sensor. The square LED PCB array should just press fit in and now looks nice while toning down the brightness of the LEDs while making them even easier to read IMO. Granted toning them down could be done through brightness changes in the code, but…YMMV if you're not savvy or you just like the glow through diffuse effect better than direct LED viewing.

The photos of the white case with standard LCD display are not mine and come from the original designer of the case. I've included the original AirGradient STEP as well as ttielemans STEP package on top of my own modded files. The white with the traffic light are mine printed with cheap Geeetech white PLA. The black are all Fulament Matte Black PLA. The filament insert ‘handle’ is ProtoPasta Blood of my Enemies red HTPLA.

FWIW you can source all the parts yourself (even order/DIY their PCBs) for this sensor setup or buy one of their build kits etc. They also provide a dashboard to view sensor data/history if you give it WiFi access. https://www.airgradient.com/diyshop/
