Phone mount for controller

I added a g6 case I found from gabrielebranchi since I'm using my LG g6 for the gaming. I also used an m3 20 screw with a corresponding bolt, this should fit right into the space that I made for it in the hinge. Finally the controller I used and probably works best with is this asus gamepad that I got from amazon https://www.amazon.com/ASUS-TV500BG-Gamepad-Wireless-Controller/dp/B01NBIXCPN/ref=sr_1_1?ie=UTF8&qid=1517711805&sr=8-1&keywords=asus+gamepad
