As title. It would be very nice if we can download the 3D models from anatomy lessons like this one: https://prokolab.com/course-lesson/3d-model-of-robo-skelly/discussions. I know I can already manipulate those models on web, but downloadable files have some advantages over Sketchfab: 1) Loading time. Sketchfab isn't always so fast with my internet connection. It's frustrating that I want to get a quick reference but it just doesn't load. 2) Lighting study. It's much easier to change light sources in a real 3D program like Blender. One can have any kind of lighting, like only diffuse light, or multiple direct light, etc. I don't think it's possible in Sketchfab. 3) Comparison to other models. For example one can find a high-poly model and compare it to the Proko model, to get a better grasp on which structure is simplified to which. And probably more. It shouldn't cost too much bandwidth (compared to the downloadable videos) either.
