I also love the part when people are glittering ICE. Whistling and Glitter those bastards.

Has anyone heard of “3D GUN’T” software that’s apparently being put into new 3d printers? It can apparently block prints based off the shape or whatever to prevent the printing of gun parts, and keeps tabs on who printed exactly what. It’s basically DRM for 3d printers. Also laws in certain states demanding printers be legally required to start blocking gun parts. It may be the beginning of something worse as it adds the infrastructure needed to further block “bad shapes” down the road.

If I understand correctly, this affects 3d printers that can read STL. What if someone, hypothetically, uses an open source slicer, like Orca, and print from gcode?
Good luck adding drm to a microwave to prevent it from microwaving "fish and fish adjacent shapes". 3d printers consist of a couple of motors and a hot bit. No computer in there, unless you go for the high end stuff and even then they can't run that sort of software. MCUs are clocked in MHz, but even a 10 year old computer is clocked in GHz. Even with a cloud connections, how much money have companies poured into "AI" only to have it still get things wrong? Do lawmakers expect a podunk garage team to figure out what Google, Meta, Apple, and literal billions of R&D haven't?
Since this is effectively a ban, it would result in "healthcare CEO shot by wooden ghost gun" if gun kits are still sold, because 3d printers don't print guns. They print the "lower" that has the serial number, which is legally, but not practically, defined to be the "gun". Any gun that doesn't have a serial is a ghost gun, but the point is moot.
More realistically, it would result in: "healthcare CEO shot by a 2026 special edition 9mm VEHHFU746582 on sale for 1984$, get it before it is banned" because for some reason the legislature is running on rich people feelings, and this shooting is special because of the gun, and not because of EVERYTHING ELSE.
Not super into guns but I'm a bit frustrated with the technical ineptitude of some of these lawmakers. Gun control existed before 3d printers did, this is just half assed. Feel free to correct me if I missed something.
If nothing else I feel like more people would be killed with Shinzo Abe guns and similar hardware store contraptions
Yeah, these laws are incredibly invasive, and potentially crippling to smaller manufacturing operations.

Been printing them, just need some good locations to place my boxes
A lot of small coffee shops will allow them in their bulletin board area
Anywhere in public is great. If you're in a place where ICE is less active, you'll want to package the whistles with instructions to alert the local rapid response hotline.
I've seen whistles with the number for the local rapid response hotline printed right on them. Must have been one of those fancy multi-filament printers.
You can do it with any 3D printer, as long as you orient the letters so they're at the top of the print, you can insert a pause in the print job just before it starts the layers with the letters. Then you do a manual filament swap and resume the print.
Another option is to print a QR code on them with a link to instructions/the organization.
Thanks for sharing this. This bolstered my spirit.
I liked the bit where it discusses how, regardless of the effectiveness of whistles in deterring ICE, they have proven to be helpful in regular people feeling less alone.
We always have to remember: There are a LOT more of us than them. These whistles help us remember that.
They are armed. You should be too. And wear protective gear. They've permanently blinded people on purpose. They've already executed people in the street. Notice they aren't near anyplace where bpp is active.
If you really want to fight back, learn from the Mexican cartels and Islamic insurgencies.
We have data on what works.
a whistle won't stop these goons from harming you.
No it will not, but it will alert everyone around you to ICEs presence so they can have an opportunity to be somewhat prepared.
You'll at least give your neighbours a chance to put some pants on, hide, barricade, or even arm themselves; before ICE tries to kick in their door.
It also calls others to your aid; quickly forming mob that out numbers ICE, forcing them to focus on crowd control instead of targeted kidnapping.
Intentional deescalation does more right now than having the people closest to ICE or Border Patrol agents carrying weapons.
The standard for now is that responders with guns stay back to deter massacres.
Really cool article and movement, thanks for sharing it. I’ve been printing whistles and leaving them in my little free library but had no idea there was this nation wide movement going on.
i mean, if we're printing whistles why ain't we printing death whistles
They take forever to print and use a lot of filament.
They're printing liberty ships, not cruise ships.
these are good points
