pi zero wall mount

Should print upright - large holes on top - with no supports. Should work in just about any material and on any printer.

This is compatible with [thing:1972467](https://www.thingiverse.com/thing:1972467) and probably other raspberry pi zero 1.3/W/WH cases with through-holes.

After printing, use a M2.5 screw to draw a M2.5 nut into each of the capture holes. Draw them all the way in. Then, mount to the wall. using the large screw holes. Finally, attach your assembled case to the mount, and engage the screws into the captive nuts.

__Customization__

__mountscrew d1__ is the diameter of the mounting screw's threaded portion

__mountscrew d2__ is the diameter of the mounting screw's head

__mountscrew h__ is the height of the mounting screw's head

__thickness__ is the overall thickness of the plate. If __thickness__ is too small, the mounting screw holes and/or the nut holes will not work right. 7mm is the correct thickness to attach [the case from 1972467](https://
