7.5 inch E-ink stand

Some time ago I made outdoor weather station based on Raspberry Pi foundation (Projects | Computer coding for kids and teens | Raspberry Pi). To standard sensors i.e. wind, rain, temperature, pressure and humidity I added UV index, ground temperature and Air pollution ( PM 2.5 and PM10). Data was uploaded to Weather Underground, but some sensors aren't supported (Air pollution…). So I purchased one of Waveshares excellent E-ink screen (7.5 inch V1) and designed stand for it. Stand is hollow on the bottom and there are mounts for Raspberry Pi zero w with Pi-hat. Additionally, there is option for background to improve readability of the screen, everything is tilted 10 degrees. I also use Pi shim to gain access to additional pins for connections used for Adafruit BME280 sensor which is mounted on the side for indoor measurements. The Python program is compiled in a way that outside unit is sending data over Mosquito Mqtt protocol to Synology disk station and from there it is read by indoor unit and displayed. For mounting you need:4 M3 brass inserts4 M2.5 brass insertsAdafruit BME 280 sensor just slides in the housing. There is barrier to prevent hot air from Rpi to influence indoor sensor.
