Performance Tuning

Security Settings

MAX_FILE_UPLOAD_SIZE=536870912    # 512MB in bytes
MAX_FILE_EXTRACT_SIZE=1073741824  # 1GB in bytes
MIN_PASSWORD_SCORE=4              # 0-4, higher = stricter

Core Concepts

• Library: Storage location (local folder or S3 bucket) containing models
• Model: A folder containing related 3D files (parts, images, docs)
• Creator: Content author/​designer
• Collection: Grouping of related models
• Tags: Organizational keywords

User Workflows

Initial Setup

1. Access web UI at http://server:3214
2. Create admin account (email, username, password)
3. Add first library (path inside container, e.g., /​libraries)
4. Scan runs automatically to index existing files

Scanning

• Scan for new files: Detect new folders/​files added outside Manyfold
• Rescan all models: Re-check existing models for problems/​metadata

Uploading

• Upload ZIP archives (extracted as separate models)
• Upload individual STL/​OBJ files (creates single model)
• Progress shown during upload, extraction happens in background

External Integrations (v0.118+)

Import metadata from Thingiverse, MyMiniFactory, Cults3D:

1. Configure API keys in Settings > Integrations
2. Add link to model page
3. Click sync icon to import metadata/​images
4. Or paste URL in search bar for direct import

Supported File Formats

See references/​supported_formats.md for complete list.

3D Models with Preview: STL, OBJ, 3MF, GLTF/​GLB, FBX, PLY, 3DS Slicer Files: GCode (preview), Chitubox, Lychee Images: PNG, JPG, GIF, WebP, SVG, TIFF, BMP Documents: PDF, Markdown, TXT Archives: ZIP, RAR, 7z, gzip, bzip2

Troubleshooting

Container won't start

• Ensure SECRET_KEY_BASE is set
• Check PUID/PGID have read/​write access to mounted volumes
• Verify Redis is accessible (for full image)

Files not appearing

• Check library path matches container mount (not host path)
• Run manual scan from web UI
• Verify file extensions are supported

Permission errors

• Match PUID/PGID to owner of library folders
• Ensure container has write access for temp files

Health check

wget --no-verbose --tries=1 --spider http://localhost:3214/​health

Reverse Proxy

Set RAILS_RELATIVE_URL_ROOT=/​manyfold for non-root paths.

Required headers for HTTPS proxy:

• X-Forwarded-Proto: https
• X-Forwarded-For
• Host

Note: Federation requires domain root (no subpath).
