This is the 3D-printed case from my build of a local PM1.0/PM2.5/PM10 air-quality
sensor that reports straight into Home Assistant via ESPHome – no cloud, no app.
What fits inside:
- ESP32 DevKit
- Plantower PMS5003T (particulate matter + temp + humidity)
- SSD1306 I²C OLED (128x32)
The PMS5003T air inlet/outlet is left open so airflow isn't blocked.
Designed in FreeCAD; the editable source (.FCStd) is included alongside the STLs
so you can adapt it to a different board or display.
Full wiring, pinout and the complete ESPHome YAML are in my write-up:
