Do 3D-printed Spotify keychains actually scan with a smartphone?

Yes! When printed with high contrast between the background base and the raised code bars (for example, white bars on a black base or black bars on a white base), the Spotify mobile app camera scanner can easily read the code and instantly play your song.

How do I print a dual-color keychain on a single-extruder 3D printer?

You can easily print dual-color keychains on any standard single-extruder printer (like Ender 3, Prusa MK3/MK4, or Bambu Lab) by adding a pause or filament change command (M600) at the layer where the base ends and the Spotify code bars begin. Slice the STL in PrusaSlicer, Cura, Bambu Studio, or OrcaSlicer and insert a filament change at the bar height.

What 3D file formats does Printune provide?

Printune provides universal STL files for immediate slicing and 3D printing, as well as STEP base files for CAD designers who wish to import and modify the geometry in software like Fusion 360, SolidWorks, or Blender.

Is Printune free to use?

Yes, Printune is 100% free and open source. You can generate unlimited keychains directly in your browser or download the standalone desktop version for Windows and Linux.

Is Printune affiliated with or endorsed by Spotify?

No. Printune is an independent fan-made utility for 3D printing enthusiasts and music lovers. Spotify is a registered trademark of Spotify AB. Spotify Codes and their trademarks are the property of Spotify AB.
