Parametric Pan Pipes - any scale you like.

thingiverse

A Pan Pipes tool converts a list of frequencies to a set of Pan Pipes, enabling unique tunings and scales. An example is the equal tempered C scale. Note that longer pipes may be needed at lower frequencies; ensure your printer can accommodate them. Verify absolute pitch with a single pipe and tune accordingly for clear tones. Potential issues include leaky pipes, which can be resolved by increasing wall thickness or filling with acrylic varnish. Recommended printing parameters are 0.8mm radius, 2mm wall thickness, and 20% fill density. The SCAD program uses 'radius', 'wall', and 'notes' (frequencies in Hz) as parameters. Pan Pipes, the simplest wind instrument, rely on open-closed pipe structures that resonate based on calculated lengths and frequencies.
