Who wants 3D printed whistles to give out in their community? Let’s connect people with 3D printers and people who need whistles in this thread.

Thank you for sharing this. One of these could save someone’s life. If I had a child in school whom I feared could be attacked by federal thugs on school grounds, I’d give this to my child and tell them to use it.

Usual caveats: this is just a thread to connect people, I am not vetting people in this thread myself, please use common sense and *communicate with Signal whenever possible*.

Do NOT give people home or business addresses in Bluesky DMs. Bluesky DMs are not currently encrypted. You should only do that in Signal.

3D printers can churn out an amazingly large number of whistles for very little money. bsky.app/profile/scoi...

They're roughly between 4-5 grams each, so to be conservative assume 200 per 1 kg roll if you're not switching colors. You can get cheap PLA for 11-13 bucks, so we're looking at 800-1000 whistles for $50

Seconded, these are the best I've found, loud as heck and a very low cut in pressure (many of the LOUD whistles take a lot of breath to get that volume, but these are LOUD wirh a very modest breath pressure).

No this one is not the best, uses too much filament. You want the flat whistle from maker world, I’ve printed thousands and its faster/just as loud/cheaper.
