Indoor air quality monitor (snap-fit)
thingiverse
My 3D-printing philosophy: Things should print without supports and snap together whenever possible. Based on the airRohr project, this enclosure is a great (indoor) home for the project laid out here: https://sensor.community/en/sensors/airrohr/. The recommended pipe fittings were not readily available in the US, but provide much better protection from the elements than my case full of holes does. The 3d printed case, however, looks nicer and is smaller. The enclosure contains a particle sensor (nova SDS011 PM2.5/PM10), temperature/pressure/humidity sensor (BME280), and a microcontroller (nodeMCU v3 / ESP8266). See sensor.community link above for assembly and software instructions.
