3D Manager
3D Manager is a native model-library tool built for makers. Your files stay exactly where they are — it watches the folders you already have (local, iCloud Drive or Dropbox), generates thumbnails, extracts embedded 3MF previews, and detects duplicates by content hash. Supports STL and 3MF (including Bambu/Orca slicer files), with tags, collections and ratings synced across Mac, iPhone and iPad via iCloud.
