I designed this ST16 Platform to work with the CasePro lanyard. When I first attached the CasePro lanyard straps directly to the ST16, I found the clips were sometimes in the way of the camera and video buttons. So I made a few prototype platforms to place the attachment points outboard of my hands. This is what I finalized on. The lanyard straps are out of the way of my hands and don't interfere with any of the ST16 controls. All controls, including the sticks are easily accessible. The 2 holes on the back of the platform allow the ST16 cooling fans to operate normally.
