You can buy plastic whistles crazy cheap on AliExpress. But yeah you can print them.
As a piggyback comment. I designed a reusable retractable protest sign handle that uses very little filament. It's free. On printables, makerworld, and thingiverse.
Just search "protest handle" on the sites. Only one that exists as far as I know.
FREE model. And low filament use. Cost about $1 to print.
I will say in windy Chicago I did have 2 snap. But because of the way it's made, I only had to reprint one piece and re-assemble.
They are of decent durability.
But a big sign and Chicago wind was a challenge to the design which I prioritized printing time and low filament use.
I've made about 8 total and none of those broke for other people using them or myself.
