Manyfold
Manyfold is a self-hosted web app to organize, preview, and share 3D models for 3D printing, with tagging, metadata, and disk reorganization tools.

Manyfold is an open source, self-hosted web application for managing a collection of 3D models, with a strong focus on 3D printing files such as STL and OBJ. It helps you organize, preview, deduplicate, and share models through a browser, including optional federation features.
Key Features
- Interactive in-browser 3D previews for browsing and inspecting models
- Organization via tags, creators, collections, and rich metadata (notes, source, supported/unsupported, and more)
- Sharing controls for public or private access, plus following content from other instances via federation
- Automated “tidy” workflows to reorganize and rename files on disk based on metadata
- Troubleshooting tools to identify duplicates, nested models, and inefficient formats
- Background job processing for asynchronous tasks (such as processing and analysis)
Use Cases
- Build a searchable home archive of 3D printing models for a makerspace or personal library
- Maintain a team collection of approved print files with consistent metadata and naming
- Publish selected models publicly while keeping private collections restricted
Limitations and Considerations
- Federation features are present but may require additional setup and operational understanding
- Production deployments are designed around PostgreSQL, while SQLite is mainly used for development
Manyfold is a practical DAM purpose-built for 3D printing collections, combining fast visual browsing with metadata-driven organization. It fits well for individuals and teams who want a structured, shareable library of models without relying on third-party platforms.
