Porter Robinson Nurture Spotify Code Keychains

Some spotify code keychains for the songs on Porter Robinson's album, Nurture. There is also one code that links to the album itself.

In order for the codes to work correctly, you need to use a color change at the layer the code begins printing. If you don't want to or can't use a color change, you could possibly paint the surface of the code after printing. I personally used a color change though.
