Self-hosted Express + Postgres app for organizing STL/3MF/OBJ/etc. with: - Model/file library, tags, collections, print settings - URL import: Thingiverse (API), Printables (GraphQL), MakerWorld (FlareSolverr + token), cubee3d/other (metadata + manual files) - In-browser 3D viewer; 3MF rendered via Python/trimesh GLB conversion - Auto thumbnails, license/commercial-use tracking, in-app editing - Settings (API tokens / FlareSolverr) stored in DB with .env fallback Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
