    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.

    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.

      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.

          Heat stamping might be quickest alternative. Should be rugged and aid low-vision use.

          Full brass letterpress type sets and die can be pricy, but the cheap leather iron kits at craft shops commonly include small metal alphanumeric types that could be set (clamped) and affixed to your stamp (burning/soldering iron or pliers + hot plate/stove).

            if it’s not multicolour then you can just make the printer leave indents for the letters (or print extra material to have it raised)

            no need for post processing or extra equipment which slows down the process and adds extra work

          Do you have to prime 3d printed objects? If not, just print the number and like dip into water paint. Ideally you could print a lip with higher numbers so only the top of the numbers get painted

              Only issue with black marker on 3d prints specifically is the ink tends to wick around the layer lines. Still works but doesnt look great. Paint markers are usually my goto

                Yup this issue you can see in my picture. I was hoping paint markers would have been viscous enough to not bleed but it did anyways. Not that big of a deal for a fire and forget box of whistles.

            If it’s bevelled text you can swap filament during print to make it stand out / easy to read.
            Only problem is that you have to baby sit the print, which could slow down production considerably

      Not saying anyone’s doing this for whistles in particular, but you can make PET filament from salvaged bottles. And VHS tape, but I really doubt anyone is going to be able to print something that needs to be as precise as a whistle from VHS tape. From what I’ve seen it comes out… lumpy.

      This is incorrect, the author says that he prints whistles for 5c a pop, which is cheaper than dropshipping from China. This also implies that 3D printing whistles at home in that fashion is more productive when one doesn’t live in China (or next to a whistle factory).

          Most of the time cheaper products are better for the environment when they’re durable. A very simple whistle has hardly any parts that could fail easily and is therefore durable.

          See the cost of veganism, prefab buildings or electric cars. If local production and local distribution of objects saves transport and handling expenses, which come from people expending time, keep in mind those people need to be fed and have to get to work somehow, then that is a fact.

          I’d imagine the lack of being shipped many thousands of miles is what makes them ecologically friendlier.

    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.

    An alarm won’t stop a break in, and 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.

        I mean, the Black Panthers started because people realized that peaceful unarmed protests would be violently busted, but peaceful heavily armed protests were politely watched from across the street. Blindfiring into crowds is a lot less appealing for cops when the entire crowd can return fire.

      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.

      You both make good points, but prevention is better than de-escalation or alerting. Being known as protected is a preventative measure.

      Of course alarms/monitoring and response (de-escalation) are very important. But stopping it before it starts should get attention as well.

        Not everyone can afford big guns and heavy armor; nor have the training/licensing required to cary/display them.

        3D printed whistles are a cheap and easy aid. Every bit of resistance helps.

          Exactly.

          Recommending that random untrained people go around armed is a recipe for disaster (see: ICE’s random untrained people going around armed). It’s irresponsible, at best.

          I read these people as if they’re calling for violence but trying to skirt the line in a way that doesn’t get them banned.

      I think they’d be great for distraction and irritation, but at the same time, they’re not as god for signaling and alarming, and, I would imagine, would desensitize us to human screams.

        If you would rather invest in a quality whistle for the one that goes in your own mouth, I recommend an ACME Thunderer.

        As used by gym teachers and drum majors, (not Wile E. Coyote) they have a satisfying roll of authority.

        It’s not going to be significantly unsafe. It’ll shed more microplastics and is more likely to grow mold due to the surface texture, but if you’re inhaling through the whistle you’re using it very wrong.

        That said, an injection molded whistle can be bought by the thousand for a few cents each.

        The biggest concern with these come from the fact that it’s hard to decontaminate 3d printed stuff due to the texture, as far as I can tell? PLA, and PETG are food safe, but 3d printing does leave a texture that’s hard to fully clean, which can cause problems over time.

        For microplastics: You’re getting a lot from a lot of sources, and as with anything it’s an “Is the risk worth the benefit” situation
