This is a simple, 32mm pipe attachable, multi-sensor enclosure, for outside projects.

Remember, if you are printing with PLA, you MUST spray some paint, resin or something resistent to the environment. PLA it's not water proof, it tends to absorb water.

You have to print it with the fins pointing upwards.

The sistem works perfect. the sensor I put inside are the MQ2 and the Shinyei PPD42. It resist below 0°C and heavy rain.
