5 Jan 2024 – Prototyping Motor Bracket
I had decent success making a NEMA 17 Hole pattern module in OpenSCAD using Chat GPT: https://chat.openai.com/share/a0d364af-3011-4e7f-8a61-1e7bf7427703
I’m now less than enthusiastic about using Chat GPT for OpenSCAD. I spent more time debugging than if I would have done it by hand: https://chat.openai.com/share/030179ed-e2b7-48c2-84e0-8d09a41428c1
