This is my C64 Silver Label print with both the regular and power badges, that I made after not being able to find a good option out there… This won't fool anyone into thinking you've got a real silver label, but it does look pretty good if you ask me, and was a great replacement for the badge I had with peeling paint.

The STLs have separate parts for coloring that you should be able to select, I was able to import it into my slicer, split into parts, and select different colors that way.

This works best using a 0.2mm nozzle for sharp corners, layer height doesn't matter that much, but thicker layers can lead to some smudging, so use your best judgment.

I also recommend that you use a single wall loop for the badge part, with a Monotonic Line bottom surface pattern, but the letters are probably best as a full concentric pattern (I just used the default 4 wall loops, same result)
