In your first sentence, you answered your question.

CAD is complicated, yes. But the biggest pain point is that engineering requires a lot of adjacent knowledge about material, tolerance, mechanical design, tooling, and so on. Making things requires patience.

CAD is the easy part.

Check your local library, a lot of them have one and can help you get started. It's usually pennies to print too. I printed an adapter for my coffee grinder at my local library a few weeks ago and it took 2 days and cost me $4. Fantastic stuff.

I've been telling myself that for as long as 3D-printing has been consumer tech (about 20 years ?) and now it's shifted to "I'll borrow one my friends' printers if needs be".

In truth every time an issue fit for 3D printing has come up in my life, I solved it easily with wood and cardboard. I'm starting to recognize I might be a craftsman at heart.

Even with my old/cheap Ender 3 Pro, I printed something overnight took 13.5 hrs, there it was

I thought the same thing while reading this. But I worry that I'd get one and it'd just sit on a shelf somewhere collecting dust.

You might already have one, and just don't know it :-) If you don't, it's much cheaper to get one that the author considers a 3D printer.

From TFA:

> 1. I like to think that all printers are 3D, unless it's a printer in Flatland.

Skip the too-cheap entry level and get something reliable. They’re great to have handy, but easy to fall into maintenance and calibration hell. Modern 3D printers have enough sensors and smarts to self-calibrate reliably. That’s essential to make it a tool and not a tinker toy.

Turns out attempting to pay the bills on unix philosophy didn't go very far.

I'm going to lump together proprietary and for-profit software a little because I rarely see exceptions:

Proprietary / for-profit software is made that way, yes. There's no other way you can do it, given the incentive landscape. You take the huge base of FOSS code and spend as little effort as possible to build a thin little layer of moss on top. You respect the customers as little as possible to keep them around. You fix bugs as little as possible. You use other proprietary services that spy on your customers, like Sentry and Firebase, because privacy costs money.

Free / libre software has to compete on its merits. If a project isn't useful it doesn't grow. But not growing is okay. Some projects accrete over years, like a pile of stones forming a cairn. They don't need to squeeze money out of people to live because they aren't alive. They don't have to "eat".

I'm mixed on the Unix philosophy. It makes a lot of sense when you're building CLI tools that a hacker is going to plug together, because then your program is really a function in a programming environment that spans one or more entire computers. Tools like ripgrep, jq, curl, they're all great, I love them. A good function does one thing and does it well.

But just as often, I'm okay with huge software that does a lot. Web browser engines are evolving into universal GUI / IO frameworks and I'm trying to make peace with that. Systemd does a ton of stuff, but hell, so does the Linux kernel. I don't see an inherent problem with having an init system that acts like a monolith kernel for userspace. Microkernels are nifty but in the end we all ship our org charts. Maybe there's no need for microkernels if the real divide is between kernel programming and userspace programming. For the same reason, I haven't found any personal use for wasm, because wasm makes the most sense when you're connecting two pieces of code written by different teams at different times, like a GIMP plugin. I don't need wasm to plug my own code into my own code.

And for GUIs it's just been a fucking nightmare. 57 years since the Mother Of All Demos and it's still 10x easier to write `fn main()` and build a CLI program that runs on _every_ OS, rather than a GUI program that maybe runs on one OS, like it runs on Ubuntu 24.04 but not Ubuntu 22.04. What a fucking mess. GUIs don't compose, so every GUI project I've tried feels like I'm inventing the universe from scratch. It's fun but it's a stupid fucking waste of time.

Honestly browser engine frameworks like Electron and Tauri _are_ the Unix philosophy compromise. Making a GUI framework requires tens of thousands of lines of high-effort code made by experts. If a browser's one thing is "Be a GUI framework" then it allows your GUI app to just serve HTML and now it's a CLI app that runs anywhere without fucking with GTK 3 vs GTK 4 bullshit.

Sorry for the long rant. This stuff is all percolating in my head. I started with Visual Basic 6 and I still haven't seen GUIs improve since then. Phones have been a fucking step backwards, too. Everyone uses a phone but just like a mouse-and-keyboard player dominating gamepad players in a shooter game, I get a lot more done at a real desktop with a real pointing device.
