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.
I love writing that uses acronyms and never defines them.
It’s pretty easy to figure out what DLE was about from the context clues in the article. Knowing that it means Discoid lupus erythematosus and the detailed definition wouldn’t have added much imo. In fact I didn’t even care to look it up until I read your comment.
if you're referring to DLE, from the second paragraph:

> When she was diagnosed with DLE, discoid lupus erythematosus, an autoimmune condition where the immune system attacks the skin on the nose and sunlight makes it worse

edit: ah, just saw a comment from the author indicating they added that post-hoc

> I want to be honest about what happened next, because it matters

I like the project but using Claude sure didn't improve this article.

Are y'all gonna register a complaint for each and every instance of an LLM written or enhanced article anywhere?

It's mainstreamed. Spare the rest of us.

s/enhanced/diminished ... because it matters
If nobody complains, nothing changes. At the very least Claude's output should have been edited and improved, but it reads like it was mostly copy-paste.
We've got to shame this shit until it stops. LLMs are great; don't use them to write for you. Especially not in the first fucking person.
lazy writing is always valid ground for criticism…
The rapist attitude of just say yes and accept it is disgusting.
I think calling out AI is pretty 'mainstreamed' at this point, if that's our criteria.
It's kind of insulting. Like they didn't take the time to write it but expect me to spend time reading it.
Are you going to register a complaint on every complaint about LLM prose? They aren't going away. Spare the rest of us.
Yes absolutely will combat spam comments until yall stfu or a rule changes
This dude invented not one but multiple dog health care products ... with no animal product design background whatsoever! Then (with no business background) he started an entire company helping hundreds of dogs all over the world.

Maybe instead of expecting everyone to be good at everything, we cut this guy a little slack and let him use AI to help write?

I think it's possible to give someone their flowers for being a great innovator and also call them out for producing writing that's painful to read.
Absolutely.

But, did AI actually _help_ in this specific phrase? I think it's OK to point out the quirks (and even drawbacks) of AI, even if we generally support the underlying motions of the person using it.

Are managers not part of a delivery team?
My assumption is that every LLM-written article would just not have been written otherwise. That is a net good. It's also true that it's grating to read LLM-written prose.

Am I utterly mistaken or was LLM-written prose more tolerable when it was GPT-4o and Opus 3.x writing it?

The AI didnt help him write. The AI wrote very annoying prose.
It's all very impressive and heartwarming.

But that doesn't change that slop sucks to read.

Unnecessary comment. It is really heartwarming to see an individual do something in his spare time that helps 100s of being that can't speak for themselves.
I find it so much more annoying when it's on something that should be genuinely interesting - I just can't read this even though I do actually want to.
You don’t know that. He could be a terrible writer.
I'm OK with this, let's start by shitting on 100% Ai slop products and slop products with bad intentions first
I wish we could put the paw-litics aside and not be so snoot-y about the AI writing and focus on the awesomeness of this idea. Honestly wouldn’t be surprised to see it in re-tail. You’re barking up the right tree and I wish you success and a lot of kibble money.
Personally, comments like this are against the guidelines. Please either downvote and move on, or comment about the parts that are interesting and substantive.

> Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something.

> Find something interesting to respond to instead.

> Please don't complain about tangential annoyances—e.g. article or website formats, name collisions, or back-button breakage. They're too common to be interesting.

> Omit internet tropes.

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.)

My comment? Please review the username of the comment in question.

If you feel a given comment is not within community guidelines you are free to flag it. I do not believe that we agree about the substantive value of noting an article was written with the heavy assistance of an LLM. I usually look at comments prior to reading an article; it's an effective time-saving measure.

I do not accept your attempt to make a blanket ban on noting an article was LLM-written.

Where are you seeing that? I don't see the word honest anywhere on the page
Pun notwithstanding, what a fun itch to scratch! A clever single-user solution becomes it's own industry. I'd love to repeat this sort of growth myself, and find such clever solutions to real world problems.
Hmmm, something made to sit in direct sunlight shouldn’t be black or very dark.
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.
It’s not a big risk, there’s just no reason for it to be near black.
The idea is good and cute. But I wince a bit at seeing a pit with something looking like a mouth guard at a glance, as if they're not scary enough already.
We rarely use a muzzle for our shepherd but the ironic part is people keep extra distance because it looks so menacing.
My 120# K9 trained Akita got run at by a 10# French bulldog because the owner of the Frenchie let her leash unroll and then lost control. Things happened. Now, my boy has to wear a muzzle on premises, because - got threats from the HOA. I covered the bills for the baby, it wasn't its fault, but I utterly despise small dog owners that don't think theirs need no training.

Pits and the like breeds are scary. My previous 130# male Akita was almost murdered by a 40# female Staffordshire Bull Terrier. All 4 legs were shredded, the neck too. He survived. I cross the street when I see one.

“ I want to be honest about what happened next, because it matters: I never planned to sell it. I made it for Billie.”

My dog has no nose. How does it smell? Awful.
I think there will be a market for video game styles armour for dogs
Did they really have to sensor the photos of a few stitches on a snout ?

Like, why ?

It is not even a wound. This is just western internet people being hypersensitive
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
What do you mean by "market synthesis"? When I search online for that phrase, it just returns as a company name.
My guess is that it would mean "creating new markets"
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.

AI didn't really help in making this at all just the article talking about it months later. They already did a write up on their own about a year back without clauding it up.
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'd hope it doesn't get solved, because it's one of the few signals I have to the person behind the screen.
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.

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.
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.
Thanks - and congratulations. One question. What is this UV-sensitive filament, and does it really change color in both directions as quickly as the video shows?
FWIW I read the whole article now, so can’t compare to before, but I never thought it was written using AI. Congrats on the product it’s really wonderful what you achieved.
Wow, that is a great story! Really like how you used tech to treat a health issue. Keep up the good work!
It's specifically against the guidelines to post LLM-generated comments here [1]. LLM-generated articles on 3rd-party sites, we're more lenient about 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 almost 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.
I would be concerned about the lead in 3d prints. They are not food safe.
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?
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
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?

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.

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.

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.
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.
I wonder if microplastics ingestion is a thing to be wary of.
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
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.

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.

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?

Wasn't part of the point of the post was that this is a passion project? It's not a viable business.
