Update:
From what I can tell looking at the MK4S R2 parts, they haven't changed at all. So the MK4 dustcovers should fit just fine on the MK4S.
Unless if the X-axis go lower down on the MK4S than MK4, then it might be a problem. But I can't verify that yet.
So If someone gets the MK4S upgrade please let me know if there are any issues.

Continuing with the dustcovers I made for the MK2 and MK3, I made this new one that should fit the MK4 Z-axis mounts.

If someone prints it I would like to know if the general tolerances work or if some part is way off. And if the bottom pegs are too long.
On the side of the bottom pegs that lock into the Z-mount screw holes, there is a small added protrusion to give it more grip.
 

The tolerances of those worked fine me, but let me know if it's to loose. Then I'll just extend those protrusions, and then anyone who thinks they are too tight can just scrape them off.
