    Ai article or not. Today I decided to look at the good side of life. Product solves a niche problem. Thumbs up.

      Enabling more people to solve more problems is a great benefit to everyone, even people who don't like AI. I'm using AI to solve problems for me, and I hope more people continue this trend.

        That's exactly what moves AI tech out of market frenzy to market synthesis
        • rationalist5 hours ago
          What do you mean by "market synthesis"? When I search online for that phrase, it just returns as a company name.
          • tomrod4 hours ago
            Hey, I've tried to respond to your comment twice now but it looks like the AI/LLM checks are overcapturing any sense of structured writing. So a little less structured. Carlotta Perez, an economist, wrote Technological Revolutions and Financial Capital in the early 2000s. https://en.wikipedia.org/wiki/Technological_Revolutions_and_.... The installation phase starts with "irruption" and ends with "frenzy" which I think think is where the market is now. Then comes the deployment phase of synergy/synthesis to maturity, where valuation of new tech realigns to productive capital. In between frenzy and synthesis is where the short term pain happens. It's related to the hype cycle but is distinct enough to call out.

      This is exactly the type of niche service that modern technology enables. Without that tech (3D printing, the internet, AI) things like this are simply more likely to just not exist because it would be impossible to make the economics work.

      This is a net gain all around.

      I wish AI solved the problem of writing like shit. It REALLY bothers me how bad AI writing is and I'm not at all negative about the technology itself. I love AI, I just don't like the side effect of all this garbage content being regurgitated on the internet right now.

    I wouldn't attach it to the neck, when the head moves with respect to the neck the nose guard pushes, slides, pulls on the sensitive area.

    Better to have some part hook at the back of the head or any bony protrusions on the sides or back of the head, perhaps in the vicinity of the ears.

    • conductr5 hours ago
      Having owned many dogs and varying DME devices... I don't think that would work, dog would slip out of it easily. If you leave just a little slack the dog can move head without much consequence. Dog will adapt to it if it limits motion and it will likely be minor.
    • rtkwe6 hours ago
      That would have to be a lot more custom fitted to the dog. It's not the best but the neck attachment is a lot easier. Also it seems to work just fine from the large amount of users it's gotten too, I bet the distance doesn't actually change that much.
  • mixmastamyk7 hours ago
    Hmmm, something made to sit in direct sunlight shouldn’t be black or very dark.
    • rtkwe6 hours ago
      What's the big risk though? Plastic has pretty low conductivity so the surface in the sun might get a little warm but the whole thing will take a long time to heat up. Same thing keeps it from being very dangerous to touch, plastic transmits the heat it has to your hand more slowly too. Plus most dog noses are already black so you're not even really changing the absorption of the area much. If the nose can carry away the heat of the sun directly hitting the nose skin it can do the same for it creeping through the plastic nose guard too.
    • anamexis7 hours ago
      Like dog noses?
      • smt886 hours ago
        Dog noses are attached to a large bag of water with a liquid cooling system, so they're not hot to the touch.

        A chunk of plastic can easily get painfully hot to a sensitive piece of skin, like a dog nose.

    I wonder if microplastics ingestion is a thing to be wary of.
    • jmull6 hours ago
      Microplastics shouldn’t make the list of things to worry about here.

      For one, we don’t really know how/why microplastics are bad, or how bad. If they have significant bad effects, the mechanism is slow and subtle, so unlikely to affect dogs (who, very sadly, just don’t live that long).

      Second, the incremental increase in microplastics from this device would be very tiny compared to typical exposure estimates.

      When you balance the very small risk against a tangible benefit, they answer is clear.

    • bunderbunder6 hours ago
      If it is, we should probably start by worrying about chew toys.
      • spankibalt6 hours ago
        Yeah, you're probably right... at this point it'd probably be a drop in the ocean for any respectable city pooch lol
    • Perz1val6 hours ago
      I wouldn't worry about that, but about bacteria colonies inside the print. Sure dogs already eat random (and literal) shit, but if it's placed on an already inflammation prone nose, maybe it should be a some special material. Bacteria don't grow on metals, maybe it can be some silver ion filament or maybe at least solid resin
    • smt886 hours ago
      Dogs likely don't live long enough for microplastics to be a big problem. We haven't seen an increase in cancers in dogs in recent years like we have with people.

      They're main exposure to microplastics would be from toys, water, dishes, and low-quality food, anyway. This nose guard would be a small drop in the bucket.

    DLE, I had never heard of it. Something like lupus and it needs protection from the sun. One smart guy to come up with a simple solution.. Very good use of 3D printer.
  • bhhaskin6 hours ago
    I would be concerned about the lead in 3d prints. They are not food safe.
    • terribleperson3 hours ago
      Do napkin math on how much lead is actually in a 3d print. Then think about the exposure that actually translates to, since most of that is buried inside a print.

      We're talking micrograms per kg with a brass nozzle, unless you're printing in an abrasive filament. Possibly less - nozzle wear with non-abrasive filaments is very minor. If you're using a steel nozzle... Well, besides the fact that your steel nozzle probably doesn't contain lead, you're looking at an order of magnitude less wear or better.

      Or, look at https://pmc.ncbi.nlm.nih.gov/articles/PMC6530847/ for a worst case scenario.

      Lead in 3d prints is not just overblown, but a total non-issue outside of a laboratory context.

    • rtkwe6 hours ago
      Lead isn't the reason they're generally not food safe, it's the additives they use to make the plastics more printable.

      Why are you concerned about the food safety of this though?

    • hingler366 hours ago
      I've heard of 3D prints being not-food-safe for a host of reasons, but lead is a new one. How does lead get into the filament? Care to share an article?
      • sokka_h2otribe6 hours ago
        Mostly from some nozzles with leaded brass components, but lead is probably very small component and I'm not sure is the main reason why something printed isn't food safe. Mostly I think it's not food safe because it's not really a traceable chain, has very high surface areas, lots of bacterial pockets, generally hard to determine if it's food safe or not.

        But wrt to lead, it would mostly be in brass components

        • hingler364 hours ago
          The bacterial pockets are the main reason I know of, and it doesn't seem like there's enough lead in the nozzle allow to really matter
      • bhhaskin6 hours ago
        It's not only the filament, but the extruder.

        The CDC has some good info on 3D printers, but they don't mention food safety: https://www.cdc.gov/niosh/publications/numbered/2024-103.htm...

        Here is an article on the food side of things: https://spoolhound.com/food-safety-guide

      • Perz1val6 hours ago
        Out of the random materials like ground seashells or exotic metals like tungsten I don't think anyone has ever made a lead-fill composite filament. And that is what I call a missed opportunity

    Author here. Thanks everyone for being mean, I mean that in the best way :)

    Fair points. I’m a designer, not a writer, so I used an LLM to help write it. The story and the dogs are real. After reading the comments I removed the parts that felt off and defined DLE (discoid lupus erythematosus, an autoimmune skin condition made worse by sun).

    My dog Billie has it, and that’s what started all this. I made the cover for her, shared it free, and it grew from there.

    • tomhow6 hours ago
      It's specifically against the guidelines to post LLM-generated comments here [1]. As for LLM-assisted articles on 3rd-party sites, we're more lenient about them because we can't always expect people to follow our guidelines on their own site, and sometimes the substance wins out even if an LLM is used to "polish" the writing. But you can see what happens when an article is posted that has obvious LLM-smell; the discussion ends up being much more about that than the article's content.

      > I’m a designer, not a writer

      Most people are not "writers" but anyone can write their own story in their own words, and it's always much more charming than the output of a text-generation tool, especially when the topic is something you did for your pet :)

      I don't think you need to make it DLE exclusive. My dog gets fungal infections on his nose and this would probably help. Although TBH I haven't gone looking for solutions.
    • bhhaskin6 hours ago
      I would be concerned about the lead in 3D prints. Even if you take proper precautions (which is very difficult because it's the material in the extruder and filament) they are not food safe and easily grow bacteria.
      • randomblock15 hours ago
        Lead isn't a concern, it's at trace levels when using brass nozzles and steel nozzles are now pretty common (OP has a Bambu). That being said, bacteria should be a concern and these should probably be cleaned pretty often.

            It's also worth noting that the article has been edited in the last hour. Some section headers read a lot more clearly and naturally now (which is awesome!).

          I dislike one-shot LLM prose as much as the next person, but there's no chance this use case ever goes away. Writing is difficult and takes a long time. Using an LLM to write for you gets your message across with the least effort. It's here to stay. Our only hope is that the models simply start writing better.
          • autoexec6 hours ago
            > Writing is difficult and takes a long time.

            It gets a lot less difficult when you don't outsource it to a chat bot at every opportunity. Communication matters. If you do it badly because you let a bot that can't write do it all for you people should complain. The fact that lots of people will do it doesn't mean that readers should lower their standards.

            I'm never going to complain about people using AI to write their private documents, but if someone publishes something, explicitly for others to read, and what they published is annoying to read and that wasn't the goal of the "writer" they should probably know about it. Even if they never check the comments, those of us who were made to read that slop can commiserate with each other.

          • randomblock16 hours ago
            Sure, it's here to stay. But the least effort solution is often not the best one. I would also argue it gets the point across with the least effort on the writer's part, but the most on the reader's. LLM prose is not easy to read and often not interesting because we're all used to slop. And I like a little human touch. I don't know if LLMs will ever be able to replace the individual human style differences.

        It's not a shallow dismissal. Writing quality is core to the value of an article.

        It's likely that but for LLMs, the article would not have been written. I'm glad it was written. It's also true that it's unpleasant to read LLM-written prose for those of us who have to read it all day for work.

          Do you think your comment is a good critical comment that "teaches us something"? If not, it qualifies as a shallow dismissal according to these guidelines, even if it's not a shallow dismissal according some other definition or criteria.

          I don't think it's shallow because writing quality isn't important, I think it's a shallow dismissal of the writing quality because it doesn't discuss anything interesting or substantive about the writing quality.

          Also, what about the other guidelines? Comments should meet all of the guidelines, not just some of them. (I do get that some of these are borderline.)

    You sold 500 at $20 a piece? That's $10K. Not a whole lot of moonies these days.

    Can you build a viable business against such low sales?
