This is the classic Red and Blue Porsche Tartan Pattern seen in some Porsche automobiles.

This pattern is meant to be printed with a dark blue, red, green, and black. Here is a reference photo of the pattern in the car https://imgur.com/a/gT19nTJ

I suggest that the black in my refence model is printed in black, or a similar dark color. This is because the black in the model also provides the shading to the other colors.

I don't have dark blue at the moment, so I had to use a bright blue. That will be fixed once my supplier has dark blue in stock.

This is a complicated first layer, so make sure your bed is clean, and you have perfect adhesion.

If you take the .stl files or .3mf and put into your slicer, the back piece is separate (labeled BACK), so you can make it whatever color you want. I used red. If you print directly from Makerworld, the back piece will be red also.

IF YOU IMPORT THE .3MF, MAKE SURE WALL GENERATOR IS SET TO ARACHNE or else some of the black lines will not print
