Tấm chắn Z đặc biệt cho Voron Zero “strange”

So you're building a voron zero.

But you want to prevent gunk from getting under the deck of the printer

And also you don't want to use the default physical z endstop for some reason (perhaps you have some other way of setting your z offset).

And also, you're using a kirigami bed (or other monolithic bed such as fysetc cnc).

This part, in that scenario, acts as a "z shield". It replaces the z endstop mount and the lower z rail stop.

The kirigami bed is setting a physical reference for how far apart your two little z rails / z extrusions are. You can't just design/print a part and have it fit here, if a part is going to go between these extrusions/rails it must be sufficiently "flexible" to conform to the distance set by the kirigami bed (however well/poorly that was manufactured, and to whatever spec). The kirigami bed is a single piece of (hopefully!) rigid steel, and is effectively the reference for your entire z stage.

The z shield is in three pieces. The centre piece slides into keyways on each of the side pieces. One side piece bolts to each extrusion. That gives the flexibility to install this complete assembly after the kirigami bed is installed, and have it not add any extra stress. As a bonus you can install/remove it any time you want, without tearing down the whole z.

It's inspired by things like this: 

There are a bunch of them, but all of them assume you want to use the z endstop and all of them fix the distance between your rails.
