Design a 3D-printable bracket by describing it in speech
The author needed a quick bracket printed and spoke the request to an AI, with no CAD or manual modelling, to get the part made. ·
Done with a custom-built or unnamed agent
- What they did
- Brennan needed a quick bracket and described it out loud to an AI. He used no CAD and did no manual modelling. The post doesn't say which AI or tools he used, or how the model became a printable file.
- How it went
- He says the bracket got made from the spoken request alone, and he calls it a very mundane design example. The post gives no dimensions, print details or number of attempts.
- Worth knowing
- The post is a short social media note. It doesn't give the tool, the prompt or the number of revisions, so you'd have to work those out yourself.
Try it yourself with ChatGPT
I need a 3D-printable bracket that does this: [what it holds and where it mounts]. Key dimensions: [measurements in mm], screw size [size], material [PLA/PETG]. Ask me any questions you need, then write an OpenSCAD script that I can export as an STL, and explain how to print it (orientation, supports, infill). Stop when the script is complete and I have confirmed the dimensions.
