Here he is in White Strong & Flexible material
I found a paper model of the old Shadowcat mech. Thought he'd turn out ok in something other than paper, so I rendered a 3D model in Rhinoceros 5, based on the paper version, and here he is. As you can see from the 3D image, each piece is disconnected, giving him movable joints once assembled. His feet have a little trouble staying on, but he has no trouble standing on his own.
