Multi tone whistle
thingiverse
This OpenSCAD script allows for the creation of a customizable whistle with an arbitrary number of tones. The length calculation function, however, appears to be slightly off. Nonetheless, it produces sound! You can print a two-note version from the uploaded STL file or modify the scad file to generate a different whistle. Notes are specified as half steps away from middle C in the "notes" array, with the number of notes set in "num_notes". Adjust whistle shape parameters by editing constants at the top of the script.
