A case for an ESP32 dev board (ESP-WROOM-32) that features mounting tabs for Kreg screws and a logo on the top. It was designed in FreeCAD and the native FreeCAD file is shared as well. It is assembled with M2.5x4x3.5 threaded heat set inserts pressed into the bottom and M2.5x12 screws through the top. I use mine as a Bluetooth to WiFi bridge to connect my Ecosense RD200 RadonEye sensor with Home Assistant.
