Ever since I bought my 3D printer, I've been planning to design a custom enclosure for this device. Until now, the wires were just a mess, constantly getting caught on things or coming loose, which caused reliability issues. I finally decided to build a dedicated case to house the microcontroller (Lolin S2 Mini), the gas sensor (MQ-135), and the temperature/humidity/pressure sensor (AHT20+BMP280) all in one.
I have successfully printed and assembled it. I tried to physically separate the gas sensor from the temperature sensor, but I might need further modifications because the operating temperature of the gas sensor seems to be affecting the temperature readings.
