alt Hacker NewsShow HN: I turned a sketch into a 3D-print pegboard for my kid with an AI agent
We have pegboards and plywood all over our apartment, and I had an idea to make a tiny pegboard for my kid, Oli. So I naturally cut the wood, drilled in the holes, sat down at the computer to open Fusion 360 and spend an hour or two drawing the pieces by hand.
Then I looked at the rough sketch Oli and I had made together, took a photo of it, pasted it into Codex, and gave it just two dimensions: the holes are 40mm apart and the pegs are 8mm wide.
To my surprise, 5 minutes later my 3D printer was heating up and printing the first set.
I ran it a few times to tune the dimensions for ideal fit, but I am posting the final result as a repository in case anyone else wants to print one, tweak it, or have fun with it too. I am already printing another one to hang on our front door instead of a wreath, so people visiting us have something fun and intriguing to play with while they knock.
This is also going onto my list of weird uses of AI from the last few months.

This looks like a great project for laser cutting, but I'm actually more interested in the peg-board itself. I would love to have a big one for the kids room that was compatible with the BRIO construction sets.
Great work.
The Agent x Parent combo has become my favorite niche in LLM space. It's unlocked so much creativity at a time where we have the least disposable time.
This is wonderful. The sketch-to-physical-toy pipeline is such a satisfying use of AI — you skipped the tedious CAD modeling part and spent that time actually iterating on fit and feel with your kid instead. That's the dream.
That's a really cool project! I can imagine your kid loved seeing their sketch come to life like that.
This looks pretty awesome! You can take up a notch and start generating Lego blocks!
For a cheap (about 500 EUR) enclosed 3D printer, what would HN recommend? I know two persons with the Bambu P2S and they seem happy with it. One of them is printing stuff daily since forever. He also showed me incredible prints using filaments with carbon inside and the result is jaw dropping (but it costs something like 6x the price of regular filaments).
Is one brand better than the other? Are they all pretty much the same by now?

This is the kind of AI use case I enjoy seeing most: not replacing the project, just collapsing the boring part between sketch and physical result.
Going from rough idea to something your kid can actually hold in one evening is pretty great.
