## What it is
Manyfold is a self-hosted web application for organizing, previewing, and sharing collections of 3D model files, focused on 3D printing. Built with Ruby on Rails and THREE.js, it offers tagging, problem detection, a REST API, and Fediverse federation.

## Use cases
- organize my stl files for 3d printing
- self-hosted 3d model library manager
- preview 3d print files in browser
- share 3d models on the fediverse
- find duplicate and nested model files
- send sliced files to octoprint or moonraker
- import models from thingiverse metadata

## When to choose
- you need a self-hosted DAM specifically for 3D print files
- you want tagging, collections, and automatic file reorganization on disk
- you want Fediverse sharing or multi-user access control
- you want to print directly to OctoPrint/Moonraker from your library

## When to avoid
- you need a general-purpose asset manager for non-3D files
- you want a lightweight desktop-only viewer without a server
- you need heavy CAD editing or mesh repair tools
