Show HN: ChatToSTL – AI text-to-CAD for 3D printing

Hey HN,

I'm a beginner at CAD so I built an app that does it for me ;) Describe a part and ChatToSTL writes the OpenSCAD code, shows a live render with size sliders, then exports the STL/3MF file. Because the output is parametric, it's easy to modify (unlike mesh models like Shap-E or DreamFusion).

Try it (needs your own OpenAI key): https://huggingface.co/spaces/flowfulai/ChatToSTL

How it works: Text prompt
