My 3D printer has learned to sing! Come one, come all, and enjoy the sounds of the season as performed by the Caroling 3D Printer!
The sounds heard are made purely by the 3D printer. As the motors are driven at different speeds, different pitches are produced. If you want to try it out yourself, you can use the midi-to-gcode converter at ultimatesolver.com/en/midi2gcode
