Zuse inspired Z1-Z2 logic gate demonstration set (improved)

### A newer version/remix of this thing is available here: https://www.thingiverse.com/thing:3552684


This is my interpretation of the operation of basic logic gates as they could be used in the Zuse Z1 and Z2 programmable calculators. The information is from pages 216-221 in the book described below. The illustrations are from the patent Zuse applied for in 1936 or by the books' author. The original Z1 is designed and build in 1936-1941. The replica/redesign is build by Konrad Zuse in 1989.
