The Masters - Fridge Magnet

For the Base file, print this with a color change on layer 16 (using .2mm layers) added via your slicer.  This can be done with any printer running Marlin or Klipper.  

The other two files can be printed separately and glued in place.  They have a .2mm offset so should work with most printers.  

I do not have a MMU printer so I adjusted the .step file to split it into multiple parts that are imbedded into each other.
