NozzleNest is a desktop application for Windows designed to help 3D printing hobbyists organize their model files. If you regularly download .STL or .3MF files from sites like Printables, Thingiverse, or MakerWorld, this app gives you a local library to keep them sorted, tagged, and ready to print, without uploading anything to a cloud service. The app includes a built-in browser that opens those model-sharing sites directly inside the application. When you find something you want to download, NozzleNest automatically scrapes the page for metadata: the model name, thumbnail image, and tags. It uses both what it can read from the page itself and, for Printables specifically, a direct connection to their backend data system to pull tags and images instantly without waiting for the page to fully render. This means your library entries come with cover photos and descriptive tags without you having to type anything in manually. Once files are in your library, you can organize them into collections, search and filter by tags, and view them in a 3D preview powered by Three.js. There is also a print queue where you can drag items into priority order, mark jobs as completed or failed, and attach troubleshooting notes to failed prints. Files can be sent directly to your slicing software (the program that converts a 3D model into printer instructions) from inside the app. A small Windows Explorer integration adds a right-click menu option so you can add .STL or .3MF files to NozzleNest directly from File Explorer. The application stores everything in a local SQLite database and saves files under C:\NozzleNest by default, though you can change that location in settings. Because this is an indie project without a paid code-signing certificate, Windows SmartScreen will show a warning when you first run the installer. The README explains how to proceed past it and notes that the full source code is available to review.
