This is a box for an Wemos Lolin ESP32 board with OLED display such as you get them from ebay or Banggood for very cheap. I took the internal features from https://www.thingiverse.com/thing:3222000, moved things around a bit and added holes for reset buttons that my board has. Also, this box is designed with a pretty sturdy snap-on lid as shown in this very nice tutorial: https://www.youtube.com/watch?v=VVmOtM60VWw It's a bit of a tight fit for the ESP board so it takes a little force to get the board in and out, but on the plus side, it does not move around in the case at all. I also included the Fusion360 file of the project, so you can adapt the design if you need to.
