- Fingerprint every file in the background: SHA-256 for all formats plus a trimesh geometry fingerprint for STL/OBJ/3MF, so renamed, re-exported or converted copies are still matched. Backfills existing files on startup. - Duplicates view groups models that share files (exact copies vs same shape), recommends which to keep, merges tags/collections/notes into the kept model and trashes the rest; groups can be dismissed. - Deleting now moves models to a restorable trash; files are only removed from disk on permanent delete or when the trash is emptied. - Per-model notes with autosave. - Search across names, notes, tags, files and designers; filter by format, source and license; include/exclude tags with any/all matching; sort and group by source or format. Preferences persist per browser. - Add node:test unit tests for duplicate grouping and fingerprints. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

# Printhive
|
|
|
|
A self-hosted web app for organizing your 3D-printing files (STL, 3MF, OBJ, STEP, GCODE, ZIP) into a searchable library — with in-browser 3D previews, collections, license/commercial-use tracking, and one-paste **import from popular model sites**.
|
|
|
|
## Features
|
|
|
|
- **Library** of models, each owning one or more files; tags, collections, descriptions, print settings.
|
|
- **Import from URL**:
|
|
- **Thingiverse** — downloads files automatically via the official API (needs a free app token).
|
|
- **Printables** — downloads files automatically via its public GraphQL API (no auth needed for free models).
|
|
- **MakerWorld** — downloads files via FlareSolverr (solves Cloudflare) + your account token.
|
|
- **cubee3d (Hive)** and any other URL — imports title/description/preview image; you add the files manually.
|
|
- **In-browser 3D viewer** (Three.js) for STL/OBJ, and for 3MF via a server-side **trimesh GLB conversion** (handles Bambu/MakerWorld production-extension files the JS loader can't).
|
|
- **Auto thumbnails** rendered from the model; embedded 3MF thumbnails used when present.
|
|
- **License & commercial-use tracking** — captured per source, with a "sellable / non-commercial" indicator (a guide; verify before selling).
|
|
- **Collections** — group models (a model can be in many); rename/delete without losing models.
|
|
- **Editing** — rename/retag, edit print settings, override commercial-use, refresh metadata from source, re-download files, download all files as a zip.
|
|
- **Notes** — free-form notes per model, saved as you type.
|
|
- **Search, filters & sorting** — search across names, descriptions, notes, tags, file names and designers; filter by format, source and license; include *or exclude* tags (match any/all); sort and group by source or format. Press <kbd>/</kbd> to search.
|
|
- **Duplicate finder** — every file gets a SHA-256 content hash plus (for STL/OBJ/3MF) a geometry fingerprint, computed in the background. Models sharing files are grouped as *exact copies* or *same shape* (renamed, re-exported, converted — or mirrored, so check those), with a recommended copy to keep. Keeping one merges the others' tags, collections and notes into it and moves them to the trash; groups can be dismissed as "not duplicates".
|
|
- **Trash** — deleting moves a model to the trash; restore it, delete it forever, or empty the trash (only then are files removed from disk).
|
|
- **Settings** — API tokens / FlareSolverr URL stored in the database (with `.env` fallback), secrets masked.
|
|
|
|
## Tech stack
|
|
|
|
- Node.js + Express, vanilla-JS frontend (no build step), PostgreSQL.
|
|
- Three.js (viewer) via CDN import map.
|
|
- Python + [trimesh](https://github.com/mikedh/trimesh) sidecar for 3MF→GLB conversion, volume, and geometry fingerprints.
|
|
- Optional [FlareSolverr](https://github.com/FlareSolverr/FlareSolverr) for Cloudflare-protected sources.
|
|
|
|
## Setup
|
|
|
|
1. **Postgres** — create a database and point `DATABASE_URL` at it. The schema is applied automatically on startup.
|
|
2. **Python sidecar** (for 3MF previews/volume and shape-based duplicate detection — without it, duplicates are still found by content hash):
|
|
```bash
|
|
python3 -m venv tools/venv
|
|
tools/venv/bin/pip install trimesh numpy networkx lxml
|
|
```
|
|
3. **Install deps and run**:
|
|
```bash
|
|
npm install
|
|
cp .env.example .env # set DATABASE_URL (+ optional tokens)
|
|
npm start
|
|
```
|
|
4. Open http://localhost:3000
|
|
|
|
Run the unit tests with `npm test`.
|
|
|
|
## Configuration
|
|
|
|
Settings live in the database (editable in the app's **Settings** menu) and fall back to environment variables:
|
|
|
|
| Setting | Env var | Purpose |
|
|
|---|---|---|
|
|
| Thingiverse API token | `THINGIVERSE_TOKEN` | Thingiverse auto-download |
|
|
| FlareSolverr URL | `FLARESOLVERR_URL` | Read Cloudflare-protected sites (MakerWorld) |
|
|
| MakerWorld auth token | `MAKERWORLD_TOKEN` | MakerWorld downloads (bearer token from your session) |
|
|
| Printables auth token | `PRINTABLES_TOKEN` | Optional; account-gated Printables files |
|
|
|
|
## Notes
|
|
|
|
- Auto-download from MakerWorld/Printables relies on their private/session APIs and can break if they change; failed/partial imports can be recovered with "Download files from source".
|
|
- The commercial-use badge is a best-effort read of the license — always confirm on the source page before selling.
