I’ve collected quite a number of STL files for 3D printing, and realized I need some better way to catalogue them, because the default Windows explorer is starting to become burdensome. I’m looking for something that:

  • Shows a 3D preview I can rotate around to see the model
  • Allows me to sort into folders
  • Allows tagging with keywords for later searching
  • Snappy search

Maybe Windows already does this and I’m just not seeing it, but I feel like my collection is at the point where I need something dedicated, similar to a photo cataloguing tool (e.g. Google Photos) or a reference manager (e.g. Zotero/Mendeley).

Any good FOSS tool that does something like this? Or a generic “better file explorer”?

  • So Nextcloud has a shockingly good 3d model viewer with a long list of supported formats https://apps.nextcloud.com/apps/files_3dmodelviewer . Here’s a quick demo video I made: https://vimeo.com/865805210?share=copy

    Unfortunately Nextcloud is a whole can of worms and not just an application you install on your desktop. But it does to all the things you asked for so, worth mentioning I guess? Tagging, sorting, and search are just features of it’s general file management though, they are not really stl specific in any way.
