Gustavo-Paris/3dprint-generator ? reverse-engineered prompt

Build me a self hosted web app where I can describe a part in plain language, or upload a logo image, and get a printable 3D model back. It should let me preview the model in the browser, adjust colors for multi material printing, and export a sliced 3mf file at the end.

I want it to work with my own AI provider, using any OpenAI compatible API, and optionally my own Meshy account for more organic shapes like characters or animals. If Meshy is not set up, it should still make the closest useful parametric version from simple shapes. Also make it save project history, let me sign in with magic link email, and keep API keys stored securely in the app settings.

Use a modern clean UI, make it easy to run locally with Postgres, and look up current docs online if you need to.
