A coworker asked me to print this for him, but, of course, he wanted it in two colors. So, I came up with multiple options:
I took the original design, removed the lettering, and inset the letters by 2mm.
I could now print the letters a different color, or I could print each letter a different color (if I wanted to do the rainbow thing).
If you wish to print the letters one by one, you will, of course, need 2 "H" and 2 "E".
I also included the .3mf file in case, for some reason, you wish to use the MMU2.
