Amogh-007-Rin/Extrude ? reverse-engineered prompt

Build me a web app that turns a single image into a downloadable 3D model. I want someone to be able to upload a picture, wait for it to generate, and then preview the result right in the browser as a rotatable 3D mesh. After that, they should be able to export the model in common formats like GLB, OBJ, FBX, USDZ, and STL.

Make it feel polished and easy to use, with a simple upload flow, clear processing status, and a clean viewer for the generated mesh. Use modern web tech so the frontend is fast and the 3D preview feels smooth. If you need current docs or examples for any of the libraries, look them up online as you build. The overall goal is an affordable, transparent alternative to paid image to 3D services, so keep the experience straightforward and user friendly.
