whistle

this is a small whistle I made, it works quite well for something designed by me i made it by taking 3 online whistle chambers and smashing them together then I would print 5 or so with slight changes then pick the loudest and repeat kinda like Survival or the fittest style, anyways these work even after being underwater is decently loud and with 3 walls it's practically indestructible.

Settings are really simple, use reasonable speed and no supports and you're good to go.

Anyway, have a blast annoying all the people in your neighborhood.

some filaments and printers don't work for it to resonate I don't know why though, but if it's not resonating try a different filament

ps. Feel free to sell this locally just not in any places online.
