30279-hub/ai-3d-model-generator — reverse-engineered prompt

Build me a simple web app where I can chat with an AI to describe a 3D model I want, like a bracket, gear, cylinder, sphere, cone, torus, or a basic building mass. It should ask follow up questions to fill in missing details like dimensions, shape, use case, material, detail level, and constraints before it makes anything. I want saved sessions and chat history, plus a clear confirmation flow where if I say Generate the model, it first shows me a summary, and only starts after I reply Confirm and generate.

Once confirmed, have it use Blender to generate the model, repair the mesh, and show me a 3D preview in the browser. I also want a way to ask for changes and regenerate through the same chat flow. Let me download the final result as STL, and support extra export formats like PLY, 3MF, AMF, STEP, IGES, and DXF when the needed tools are available. Please make it run as one app locally and with Docker, and if the Gemini API key is missing it should still work with a basic fallback. Look up current docs if you need to.
