Converted Ryan's great new MPCNC Primo design files to allow multi color printing
When printing colored areas on the bottom of the design that lack supports, magnify the XY (not Z) to something around 140%. Varies per segment. Make as big as you can without it sticking out. This allows it to bridge better for these. Also recommend changing the colored segments here to 1 perimeter.
I did not include Mirrored versions. Just Mirror Y in the slicer
The author remixed this model.
