# Printune

> Printune is a free web and desktop tool that converts Spotify songs, albums, and playlists into scannable 3D-printable keychains and STL files.

## Summary

Printune bridges digital music and physical 3D-printed memorabilia. Users paste any valid Spotify track, album, playlist, or artist URL, and Printune retrieves the official Spotify Code bar data, generating a precision 3D model that can be customized in real-time and exported as a print-ready STL file.

## Key Features

- **Spotify Code to 3D STL**: Automatically processes Spotify URLs into raised barcode heights.
- **Multiple Base Shapes**: Choose from Circle, Heart, Hexagon, Square, and Star base plates.
- **Interactive 3D Viewer**: Real-time WebGL/Three.js preview of the keychain before slicing.
- **Dual-Color Slicing Ready**: Designed for single-extruder 3D printers using a simple layer-height filament pause (M600).
- **Multi-Platform**: Available as an in-browser web app and standalone desktop binaries for Windows and Linux.
- **100% Free & Open Source**: No sign-up required, no paywalls.
