Playstation 3 Controller R1 + L1 Replacement button

The R1 and L1 buttons were missing on a Playstation 3 controller of a friend of my. Instead of buying a new controller, I decided to design and print new R1 and L1 buttons for his controller. So far they're working perfectly and I wanted to share my design with you guys. Feel free to download this Thing and fix your Playstation 3 controller. :)
