I modeled it to print each color separately. I usually print the triangles, then the frame, then the base. They are designed to print at a .1mm layer height. I used cura to align them all at the center of the build plate.
Be aware when printing with a textured build plate. In the photos Black and Gold was printed on a glass bed while black and silver was printed on a textured bed. Bed adhesion is super important for this piece.
If done correctly all the layers will fuse and you'll have a single 3 color print using a single extruder!
