Description
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.

Could you build this?
Yes This is a single maker project/workflow using multimodal prompts with an existing LLM or agent to generate CAD/OpenSCAD code from a drawing for 3D printing.
Discussion
17 comments analyzed.
Competitors mentioned: BRIO construction sets, LEGO, Prusa printers, Creality Ender 3, Snapmaker U1
Concerns raised: Pine wood too soft, causes splinters in pegboard holes, Bambu Lab ecosystem lock-in attempts, Bambu printers waking up to print gibberish, Open-source disputes around Bambu's use of Prusa/Slic3r work, Hand-drilling pegboard holes tedious and imprecise
Feature requests: Larger pegboard compatible with BRIO construction sets, Generate LEGO-compatible blocks, Printers with larger build volume and AMS (automatic material system)

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
