Music Maker is a free online resource that provides files for 3D printing woodwind and brass mouthpieces and tutorials for using those mouthpieces to learn about acoustics and music. The mouthpieces are designed to fit into standard plumbing and automobile parts that can be easily purchased at home improvement and automotive stores. The result is a musical tool that can be used as simply as a set of building blocks to bridge the gap between our increasingly digital world of fabrication and the real-world materials that make up our daily lives. An increasing number of schools, libraries and community groups are purchasing 3D printers but many are still struggling to create engaging and relevant curriculum that ties into academic subjects. Making new musical instruments is a fantastic way to learn about acoustics, physics and mathematics.
