NodeMCU ESP8266 case / box

thingiverse

This is a case for a NodeMCU ESP8266 with additional room for 3 other PCBs. I made this because I wanted to control my wireless Somfy IO roller blinds in Home Assistant. I connected an ESP8266 (NodeMCU) to the button pads on the PCB of the remote. The ESP8266 is controlled by ESPHome in Home Assistant. I learned how to do this right here: https://github.com/agvdberg/SomfyIO_ESPHome_HomeAssistant The PCB of the remote fits between the rails in the box. Because I expect to add PCBs of other remotes in the future, I have put 3 rails in the case. 4 (or less, if you're like me) M3 screws are needed for the lid and up to 4 M2 screws to fasten the NodeMCU. The other PCBs don't need any screws; they fit nicely into the 2 mm space between the rails.
