This is a Remix from @Kraemer
one extruder is enough.
The Extruder will print the stars and the letters first, then it moves to the front for a manual color change (Backgroundcolour). This behavior repeats in layer two.
Faced down to the sheet ( I used the textured sheet) there will be no layer lines visible.
I used PetG because the colors “melt better” together.
.6 nozzle (Revo), Urban Grey Prusament and Background is “Das Filament” PetG
