BB8 Red Carpet version

This is the guy I would like to build since my first R2D2 is almost finished.
BB8 appeared in SW EP7 and is the work of Matt Denton and Josh Lee.

In London 2016 the ingenious engineering behind the Red Carpet version was revealed.
And of course this is the one to build.

I have spent many hours trying to get everything right in the CAD first.
