Not quite the same thing, but recently I want to make adapter clips for connecting powerblocks to a barbell, making them suitable as weights for deadlift/benching. I have fusion 360 experience so I designed something to 3D print as usual, but the issue was that PLA even at 100% infill is pretty unsafe when holding 90lbs blocks.

The logical next step is to use metal, but that's outside of my hobby tools. I found that JLCPCB offered sheet metal fabrication but I had no experience with sheet metal designs. I went to ChatGPT and was actually really impressed by how well it was able to guide me from design to final model file. I received the adapters last week and was really impressed by how nice they turned out.

All of that to say, AI-assisted design is actually lowering the bar of entry for a whole lot of problems and I am quite happy about it.
