CO2 Monitor - SCD30 with ESP8266

thingiverse

Remix of: https://www.thingiverse.com/thing:4888691 Wanted something with more airflow for the CO2 sensor and also less cramped in case I wanted to add more sensors or outputs to the ESP8266. Also wanted to play around with the Fusion 360 voronoi community plugin and a design would print. I had larger holes initially, but then didn't print well since it has less material between the holes. Held in place with hot glue, didn't bother with hardware. Not the best print, but it works. Not using SCD30 temp or humidity since they've permanently bugged out after setting a negative temperature offset. Relying on another sensor in the room for that data.
