Lessons3D Free Lab for interactive 3D lesson ZIP exports

After you download the courseware ZIP, use the import panel inside the lesson to replace the empty model area with your own file.

1. Open Sketchfab and search for a downloadable model that matches your lesson.
2. Check the license and attribution before downloading the model.
3. Prefer a .glb file. A .gltf folder or ZIP model bundle also works.
4. Open the exported lesson ZIP and double-click index.html.
5. In the lesson, click Choose model files or open the import guide to load the model.
