About Preview3MF
Preview3MF adds Quick Look and thumbnail extensions for .3mf files, so pressing Space in Finder shows a rotating, zoomable 3D view of the model. An overlay lists triangle and object counts and dimensions, and for Bambu Studio or OrcaSlicer projects it shows the build plate, print profile and, after slicing, estimated time and filament.
The host app only needs to be launched once to register the extensions, which are then enabled under Quick Look in the Extensions section of System Settings. Builds are published on GitHub releases.
