Another Simple Fipple

thingiverse

This custom fipple is influenced by Mikaelfernstrom's innovative design. I decided to create a customizable version in hopes that users would experiment and find the ideal combination for producing a loud, clear whistle. You can also download the OpenSCAD file to use it as the mouthpiece of an ocarina or tin whistle. I 3D printed this model, sealed the end, and blew into it next to a guitar tuner; it reported the whistle was a B (noteworthy for its sharpness). I compared that result with the approximate frequency of a Helmholtz oscillator, which seemed to match perfectly. You can use this calculator for estimating such frequencies: http://hyperphysics.phy-astr.gsu.edu/hbase/waves/cavity.html#c4 To make the most out of this fipple component in other projects, print it with standard settings: 10% infill density and a single shell. Also, create a raft to ensure stability.
