I found this funny sign on the internet. Since there was no mmu version yet, I simply traced it and prepared it for multi-colour printing. This makes it possible to print the sign from top to bottom so that the prettier front side is on the print bed.
UPDATE: I added also a version for people without MMU or AMS. So you can manual change the color once at the right high.
