The ultimatate Gaming experience!You will need:The two printed parts, a M4x20 Screw i recomend ISO4768, and a M4 Hexnut. If you can`t get Metric screws you need something like 19/128" or 21/128"The assembly is very easy: Just put it together like you see in the pictures.Connect your controller to the phone: If you don`t know how, google it! I will write an tutorial if i got some time.Start playing the whole night long ;-) I would use ppsspp (http://www.ppsspp.org/) it is an awesome psp emulator. And since the OnePlus One is one of the most powerfull devices out there, you should have plenty of fun!!! I will update the design if i need to or if YOU want to. Just let me know. Thank you for liking and have fun playing!
