Printed mine on single extruder multi color mode, facing down. Use my 3mf for printing or as a guide. 

this video timestamp (21:30) could help you how to set up single extruder multicolor:

If you plan to use stl's on MK3 you need to:
-import to slicer as a PARTS not individual objects,
-rotate them, 
-scale in X and Y to 88%, to fit in build plate
-mirror along X axis (if you want to print facing down)
