I have links to youtube videos with a big thumbnail. That's good enough. Similarly a static image that links to an interactive viewer is good enough. All that's needed is a way to have the viewer launch with the model loaded, ie pass it the address to the fcstd or step file. There is actually an STL viewer already in github, and it even shows visual diffs, but I never get to use it because I consider STL to be an output format that I don't want in my source repos, only in release assets. But the fcstd file is the source, so a direct viewer for that is awesome. For kicad... it would require exporting to step and having the step be available somewhere, but it would be worth it for some projects.
