Zuse inspired Z1 logic gate demonstration set (improved, again)

This is a new version of my interpretation of the operation of basic logic gates as they could look like in the Zuse Z1 programmable calculator. 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. The Z2, Z3 and Z4 used relays for the CPU part, so mechanical gates are probably not used here.

The original described parts are simple metal strips and a pin (red, blue, yellow, green and middle gray parts), I added some guides to make the gate work in isolation. In the actual machine the parts will be different and integrated. This model is only to demonstrate the principle, not to resemble the original (destroyed) or replica (Deutschen Technikmuseum, Berlin, Germany: https://sdtb.de/museum-of-technology/exhibitions/1256/). This is an improvement of https://www.thingiverse.com/thing:3366661.

The book does not describe the actual AND, OR and XOR gates, but based on the information this could be close to the actual parts. These elements reuse most parts of my earlier attempt, and are functionally more consistent. The main difference are the floating plates (green), one normal one for the AND and two thin ones for the OR and XOR.

Animations of the operations of these gates can be found on my site: https://fjkraan.home.xs4all.nl/mechanics/zuseGates/

Notes: 

Note all parts except the (green) c and d plates are the same for all gates. The AND has one plate (c) and the OR and XOR have two (c and d).

Post-Printing

Some filing can be needed to get the internal plates to fit in the fixed plate (gray).

For the OR and XOR gate, the two floating plates are the same but one must be flipped before installing. See the animation.

The input plates are yellow, the right blue plate is the clock, the left blue plate is the output. Note the gates work in two phases; first set the inputs, then apply the clock bu moving it to the right. To reset to the initial state, reset the clock plate, then the inputs.
