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,…
I turned a sketch into a 3D-print pegboard for my kid with an AI agent launched on March 30, 2026 with 65 votes, #680 of 23,380 launches that month and more than 95% of that year's launches.
In plain words
A maker used an AI agent to convert a hand-drawn sketch of a pegboard into a 3D-printable design. By photographing a rough drawing and providing basic dimensions to an AI tool, they generated a working 3D model in minutes instead of manually designing it in CAD software. The project includes tuned dimensions for proper peg fit and is shared as an open repository for others to print, customize, or modify.

I made a tiny book using a pen-plotter and AI2025 · muffinman.io · ▲150Hey HN, I want to share a personal project: I made a tiny pen-plotted book for my wife. I did everything myself—drawings (with some help from Midjourney), plotting, cutting, and binding. I even used a 3D printer to make a helper tool. It's absolutely over-engineered, but I enjoyed it a lot. Multi-disciplinary projects, especially those with a physical output, are a lot of fun for me. The post covers the process in detail, but if you're interested in anything specific, let me know. Cheers!

GPT image editing, but for 3D models2025 · adamcad.com · ▲188Hey HN! I’m Zach one of the co-founders of Adam (https://www.adamcad.com). We're building AI-powered tools for CAD and 3D modeling [1]. We’ve recently been exploring a new way to bring GPT-style image editing directly into 3D model generation and are excited to showcase this in our web-app today. We’re calling it creative mode and are intrigued by the fun use cases this could create by making 3D generation more conversational! For example you can put a prompt in such as “an elephant” then follow it up by “have it ride a skateboard” and it preserves the context, identity and…
