ESP8266 D1 Mini OLED 0.91" Case

Finally! A housing for the ESP8266, a 0.91" OLED and a 4mm diameter hole so that sensors can be wired from the outside. It is screwed on with 4 hex socket screws, M2.5 x 8 mm, but I would recommend screwing in the screws without the cover beforehand, as they are very tight.Have fun printing!
