K8200/3DRAG CoreXY mod

This is not a mod for the faint of heart, it requires an almost complete disassembly of the printer base frame.
And probably a lot of swearing and frustration, but I am quite pleased of how it turned out.
I am marking it as a work in progress, since I plan to modify a few things to better fit readily available hardware and to come out with a bill of materials and a proper assembly sequence, eventually.
But if someone is daring enough to give it a try, here's the sources, have a go at it! :)

Here it is printing its own endstop brackets: https://youtu.be/2o1mKZOJG_4

I am intentionally only publishing the SCAD files, because you really need to know what you are doing before you tackle this. I have set up Marlin to be set in CoreYX mode (notice the exact spelling) and unless you use a recent release from the GIT repository it just won't home properly. Whenever you test movement leave the grub screws off the pinions until you are sure the motors are spinning in the right direction
