I had no way of mounting my ESS board effectively and both connect from my PC and interface to the ports so I designed a case for it and printed it on my BOT. Worked out nice protects everything and I can get to all the connections.  It can be mounted on 3 sides.  I used the face in my application so I could interface to it directly from my PC.  Attached is 3D PDF so it can be seen in detail.
