I have a home assistant with sensors in use that count the coffees per year and track the last change of fresh water. To display the numbers directly on the coffee machine, I use an epaper display with an ESP8266.

For this I needed a case with a base to put it on the machine.

So I designed this functional and clean case that provides space for the display, the ESP and all cables and connections.

The housing does not need any glue or screws to stick it together. The housing for the ESP on the back is also the stand for the whole housing.

Parts list for the entire display:

• ePaper Display 2.9'': https://www.welectron.com/Waveshare-19408-Pico-ePaper-29
• ESP8266 driver board: https://www.welectron.com/Waveshare-14138-e-Paper-ESP8266-Driver-Board
• Power supply: https://www.welectron.com/Offizielles-Raspberry-Pi-4-Steckernetzteil-USB-C-51V-3A-schwarz-EU
