I love the look of this design and have recently gotten my prusa MMU2S set up. I've remixed this beautiful motor visualizer for either dual color or 3-color printing (if you want an indication of rotation). I went with a no-brand-name white for the base, no-brand-name black for the arrows and Filamentum crystal clear blue for the indication arrow.
For dual color printing:

For 3-color printing with indication:

Happy printing :)
