I needed a small case for this particular ESP32-C3 board offered with integrated OLED display on AliExpress. I use it as a cheap, tiny display with ESPHome and Home Assistant to present small amounts of sensor data directly at the locations of interest. In addition to the onboard reset button and a red power LED, the board offers one blue LED and another button for general purpose, which can be used with the case. The reset button can be pushed using a pen through the pinhole.
The holder/bottom and lid both print without support. It is best to place the ESP board onto the lid first and, then, slide both into the bottom part. When doing it the other way around, I damaged a button while sliding the lid onto the board. The holder with hole fits a 3-mm countersunk screw for mounting.
I added Fusion360 files and also included my rough 3D template for the commercial board. Maybe someone can make use of it. You can find my ESPHome config files in this Gist and may use them as an inspiration for yours. It includes the configuration of the display offset, debouncing button, and the way I interfaced Home Assistant.
