A Freecad, laser-cut case design for the AirGradient-diy air quality monitor.
Notes:
- As there is no thermal isolation from the heat given out by the particulate sensor this is not recommended for use with an internal temperature and humidity sensor.
- The positioning of the USB port cut-out assumes the Wemos D1 Mini is soldered directly to the PCB with its USB connector in contact with the PCB.
- The 2.5mm diameter holes need to be threaded with an M3, 0.5mm pitch, taper tap, for the nylon screws.
