MMU2 Underslung Control Panel + Color-Code Clip

The positions of the color clips now match the position of the corresponding LEDs on the control panel. 

This leads to smaller clips as the overall width of the cutout had to be reduced to 66mm due to symmetry reasons. The clips are now 13mm in print height. As height of the cutout now 1.3mm is used.

The rounded end of the clips can be pushed above or beneath the cutout. On the pictures you see them below the cutout. 

Printing tipps: Print the color clips with some brim to keep them on the print blade.
