XLCD MK4 multiple colors for MMU

I took over the original stl from Prusa and added colors for the MMU like Alego did. But I preferred to keep the design of the MK3 for the letters (using bridges to make a colorful background).

To do this, I inserted colored plates inside the piece just behind the letter-shaped holes (each plate has 3 layers of 0.20 mm):

Then I corrected the angles of the bridges individually for each plate in the slicer (to optimize filling), and set a bigger purge volume (100 mm3) to keep the colors pure:
