The Spotify Codes keychain 3D model is a detailed and accurate representation of a custom keychain that can be used to showcase your favorite song on Spotify, and to edit it, all you need to do is go to https://www.spotifycodes.com/, get the SVG version of the code, import it as a scalable vector graphic into the Blender file, convert it to mesh, add a solidify modifier and perform a boolean operation to the top of the keychain, then in the slicer, you can set up a filament change or simply pause the print at the appropriate layer height and change filament.
