The problem with that is, like many people found out the hard way, that printing is the easy part and 3D CAD design is much harder.
Many people now have 3D printers to print all kinds of useful tools, though, and there are businesses dedicated to one-off prints for the very occasional repair.
I'm curious if AI will make that part more accessible. You can ask Gemini to make you a parametric openSCAD model and it can do a pretty good job for most designs I've tried. Then just plug in your measurements, export the stl to your slicer, and print.
It doesn't mean people who still don't have the interest are suddenly going to build apps.
Also, the idea that there is no more room for apps just because apps already exist is wrong. Incumbent apps would love for you to believe that.
I just vibe-coded my own pedometer app after the most popular steps app on iOS started charging for Duolingo-like "Streak Phrases". The main input was my own interest/energy/attention which is the filter for whether someone will build an app. It uses the iPhone's steps API.
Just because most people don't have the interest/energy/attention to build an app doesn't mean AI hasn't made app-building trivial.
As long as you have to do something, like open a new conversation tab in an AI app, there will always be a filter for the segment of society that will do something.
The puddle for doing some pushups at home isn't very deep yet involves a little bit of time and discomfort. Almost nobody does it despite the upsides. The conclusion you can draw from that is less about the process and more about human disinterest.
I’ll only make an app if there’s nothing else comparable out there (surprisingly common)z
They would if you could print things out of durable materials that had weight and structure. I haven't seen any 3D printers that do anything except for that light resin-plastic that feels like you could snap it easily. But if I could print a PVC section for my sink that would totally change the calculus.
You can, in fact, print perfectly well in any thermoplastic, including PVC (although it's unpopular due to toxic fumes). Nor is strength neccessarily an issue. In fact you can 3D print polycarbonate parts strong enough to scratch-build a drone - props and all.
No - the reason you wouldn't want to print parts for your kitchen sink isn't because you can't, it's because you rarely need such parts, and when you do you can simply buy off the shelf parts for next to nothing. A printer simply does not justify its overhead for most people. It's like having a lathe: useful if you're seriously into manufacturing or crafting, but not worth it if you want something pre-designed. There's just not much that it wouldn't be easier to just buy.

You and I totally would, but we're nerds!
Think of how much coaxing it takes to get the average North American homeowner to replace a leaky shower head or a spark plug. A lot of normal happy folks will spend their lives not really learning to fix things much, and that's quite alright, IMO. We don't all need to be good at everything.
As noted above, it's the mechanical design / CAD that has to be seriously learned to do anything useful.
Considering the 3D printing barrier for entry is buying, setting up, learning, and maintaining a whole new piece of equipment vs going to a website on a phone or computer everyone already has and telling it what you want in plain english, I think the comparison is lacking.
This reminds me a bit of the 2010s idea that every house would have a 3D printer to make one off repairs. Years later, this still seems far out of reach. If anything, it seems to have been settled that most non-technicals don't want a 3D printer.
Vibe coded apps are great, but unless they're hitting an already open API, they're effectively hermetic. There aren't many useful, high quality APIs out there without a companion app these days.
I encourage you to ask members of your household what apps they use which don't connect with any other apps, sites, or companies. I think we'll find the number is pretty low.
In your mind, what are some apps which don't currently exist which would be solving a bespoke household issue that non-techies will be reaching for vibe coding to solve?
I'd be happy to be proven wrong, but I'm just not convinced the puddle is very deep. It's really hard to compare taking a photo with vibe-coding an app.
