Hello,
it would be nice to be able to add Manyfold (VanDAM)
Manyfold is a self-hosted open source web application for managing a collection of 3D models, particularly focused on 3D printing.

⚡Features
Browse: view and enjoy your collection, and easily find the models you need; all in fully interactive 3D.

Categorize: Sort your templates and files by tag, creator, collection and add metadata like original source, notes, supported/unsupported, etc.

Tidy: Automatically reorganize files on disk based on your tags or other metadata, with fully customizable renaming options.

Troubleshoot: Easily spot duplicate files, nested templates, inefficient formats and more.
