Manyfold

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.
