Summary

There are 3 Files. I have included the blank keychain and plack for your costume playlists and songs, just make an SVG of the Spotify code (I used Inkscape) take it to Tinker Cad, and drop it on the model. :)
I have also included an example from my own Linkin Park Playlist.

Print with 0.28 height and the infill won't matter. but just in case set the infill to 100%.
