An Autodesk Fusion 360 export file and three STL files have been uploaded. This is a custom case for the PlayVideo. It has a general purpose Raspberry Pi 3B mounting on the bottom and the top section has holes for the PlayVideo printed circuit board. Note, the Autodesk file is suitable for anyone who wants to build a Raspberry Pi project with space above the board for a circuit and connectors. The layout fits the Raspberry Pi 3B and 3B+. 

Note one side is removeable. When in place, it holds down the circuit board. The top holds the side panel in place. The top is secured with a single #6 screw.
