Printventory is an open-source desktop and server-side management tool for 3D printing model libraries. It scans STL and 3MF files in your existing folders, then creates a local searchable database, thumbnails, and metadata—without moving or uploading the original model files. It is not positioned as a download platform, nor as a replacement for sites like MakerWorld or Printables; instead, it complements local collection management.
Features include file scanning, thumbnail previews, sorting by name/size/date, global search, tags, designer fields, print status, source URLs, and notes. Batch editing and content-hash-based duplicate detection are especially valuable for users with large model collections. In terms of formats, STL and 3MF support is fairly complete, ZIP search is still in Beta, while STEP and G-code are only listed as planned. AI tagging supports Puter, Google Gemini, and OpenAI, with Puter recommended as the free option. It can also automatically fill in some metadata from Thangs, Printables, and MakerWorld URLs. The project is built with Electron, JavaScript, and SQLite.
Supported platforms include Windows 10/11, macOS Intel/Apple Silicon, and Linux Beta. It also offers Docker/Server Mode, which can be deployed on a NAS or headless server and accessed in a browser via port 5000. The software is free and open source, mainly supported through PayPal, Patreon, Buy Me a Coffee, merch, and affiliate links. The FAQ is quite detailed, covering installation, backups, Docker, performance, troubleshooting, and best practices, making it highly practical.
Its strengths are that it is free, local-first, privacy-friendly, cross-platform, and provides metadata and deduplication features tailored to 3D printing workflows. The drawbacks are also clear: the macOS app is unsigned, Windows may trigger untrusted-app warnings, and some Linux, ZIP, and Docker/Server Mode capabilities are still somewhat experimental. Initial loading and thumbnail generation can be slow for large libraries, and syncing the database across devices may risk corruption. It is best suited for 3D printing enthusiasts, users with large model collections, and anyone who wants to centrally manage a model library on a NAS.
The collected text does not provide information on access from mainland China, download speeds, or payment availability, so its China accessibility status is unknown. Given that support channels rely on Discord and AI services involve OpenAI/Gemini/Puter, some integrations may be affected by the local network environment in real-world use. Alternatives include continuing to use local folders/NAS file management, the collection features of MakerWorld/Printables/Thingiverse, or general-purpose digital asset management tools.
