I used color changes to make the print in the photos. The included .3mf file has the 2 color change points built in.
I started with matte black PLA, then switched to a lighter color to give the lettering some contrast. Finally, I switched to the gradient filament.
I recommend using some type of gradient filament for the terrain. I used SnoLabs gradient PLA, but any gradient PLA should look great.
