Breath Flute

thingiverse

Breath flutes are musical instruments that can be played easily - they have no finger holes and you play the instrument with your breath. They belong to a class of flutes called "_overtone flutes_" which change pitch based on how much air pressure you provide. They are useful in community music sessions as well as in music therapy, therapeutic music, and a wide range of personal breathing practices such as yoga and meditation. The Breath Flute Project is an open-source project that provides highly parameterized OpenSCAD models along with 100+ pre-rendered STL files of various options and configurations. The release package also has extensive documentation (over 300 pages). A direct link to the Developer's Guide can be found at www.breathflute.com/pdf/BreathFlute_DevelGuide.pdf (63 pages / 1MB). The STL files allow users to print the 5" tall headjoints as well as custom sanding tools to facilitate post-processing. You add 3-4 feet of 1.25" PVC tube to a printed headjoint to make a complete instrument. This Thingiverse posting has a single STL file that demonstrates a full print of a headjoint. However, for several reasons, most headjoints are fabricated in three separate prints and joined with set screws.
