Ask HN: What tools do you use to create 3D print models using AI

Hey HN! I have been dabbling into some hobby projects that require designing custom 3D printed models. I have been relying on AI models, mostly GPT Sol and Astra through Codex, and giving them certain tools such as Blender MCP and OpenSCAD CLI to design.

My end goal is 3D printable designs ( .stl etc). The results have been good but not great. Iterating and improving them is such a pain in the ass. I want to know which specific tools or workflows you would recommend I should try. Thanks in advance!
