My wife and I played in the virtual world “Asheron's Call” for many years. In memory of those times I created this multicolor print.
This project does not require an MMU. In place of the MMU it prints in layers using the pause and change filament command on a stock Prusa printer. The filament changes are saved in the .3MF file.
You'll need two small magnets if you use the print as a refrigerator magnet.
I've also created a very detailed build page hosted on instructables.
