I know where I could get several hundred terabytes (maybe an exabyte? It’s constantly growing) of ultra high quality STL files designed for 3D printing. I just don’t have the storage or the knowledge of how to turn those into a model that outputs new STL files.

I’d imagine it’d require a ton of tagging, although I have a good idea of how I could leverage existing APIs to tag it mostly automatically by generating three still image thumbnails of the content, then feeding that through CLIP, and verifying that all two or three agree on what it’s an STL of, and manually tag the ones that fail that test.
