Grok-4.6 autonomously designs a print-in-place fidget toy, iterating through CAD checks
jakedahn · x · 2026-09-03
- A user asked grok-4.6 for a print-in-place fidget toy; the model authored the parts, built the assembly, and ran motion studies on its own.
- It repeatedly detected the assemblies weren't up to spec for printing in place nicely, and iterated until they were good to go.
- A striking demo of an LLM driving the full CAD engineering loop — design, interference checking, revision — with no human intervention in the loop.
