The Sketchfab presentation works very well in my browser (Firefox) but clicking on the start icon (right facing arrow in the image) in email (Thunderbird) does nothing. I did notice that it is not possible to view the piece from directly above or directly below but that is probably a limitation of the program, and isn't something we really need anyway.

It is a very effective way to show off your work.
