Minimalistic Enclosing for Raspberry Pi Zero

This is a minimalistic enclosure for a Raspberry Pi Zero W. I use this type of enclosures for the Raspberries i take with me. The second type of this enclosure is used by the "Astronomischer Verein Dortmund" (AVD) where the Pi Zero acts as a digital showcase.

The enclosure is designed for the use of four M2 * 4mm screws.
