Train Whistle (pocket size, 4-tone)

thingiverse

This is a 4-tone steam train whistle of my own design. Small enough to fit in a pocket, but pretty good sound. Should be relatively easy to print without supports, tho may need cleanup after.The top of the whistle has a spot to feed a string through, for a strap/lanyard/necklace.V2 has a wider/deeper tone range, and fully utilizes all available internal space, so it should print faster & use less material. There can be a couple tricky moments while printing V2, but it should get past them ok, and it's easy enough to clean a few stray strings out of the openings, after the print is done.Update, sometimes the high note on V2 didn't work right, so I lowered it's tone to give it a better chance. V3 seems to be a bit more reliable in that regard.
