Scans local STL, 3MF, OBJ and ZIP archives to create a searchable library with 3D previews, metadata indexing and duplicate detection without moving files

modelist.appPersonal UtilitiesAug 2025Peter Pohar s.p.

The product is a desktop application that scans local STL, 3MF, OBJ and unopened ZIP archives to generate 3D previews, searchable metadata and duplicate detection, solving the problem of locating models spread across folders, downloads and slicer libraries. It is for individual makers and designers who keep personal 3D print libraries on their own computers. It is positioned against file managers, single-slicer libraries and self-hosted Docker tools by running locally without moving or modifying files, requiring no account or server, and indexing archives without unzipping.
