playstation 4 - PS4 - docking/holder/charger for 2x dualshock 4 controllers

I got a PS4 last weekend, and I needed a holder/charger for my controllers. I did this quick-design in Solidworks and printed it :-)
there is a hole in the back/bottom, to guide charging wires to the top/middle point, so it's not only a "holder" but also a charging station ...
