Enable quick look of 3mf files directly in your computer - the standard 3d-printing file format that is missing by default.
3MF is the modern replacement for STL in 3D printing (but macOS shows it as a blank icon.)
3MF Viewer gives you an instant, native preview of any .3mf file, colour and all. Press Space in Finder for a real 3D Quick Look, or open the app to orbit and inspect.
