I designed this enclosure for my project "Temp2IoT". It can be equipped with a WeMos D1 mini and provides cable outputs for a USB cable for power supply and another for a DS18B20 temperature sensor. After assembling the two parts of the enclosure it can be screwed to a wall with two screws.

For a better appearance and recognizability of the logo, the upper part can be printed in two colors, the color change must be at 0.6 mm.
