Xbox 1 LB/RB combo shoulder button

This is an improved versions of the 2 button Xbox 1 shoulder button piece RaffoSan posted in the comments of his replacement.

I added a groove in the middle for it to sit on the plastic supports, and I opened up the 2 holes that fit in the faceplate a little bit.

I had to route out the inside gap a little bit more to fit the controller. I may get around to updating it on here, but we got it to fit my roomate's controller. It probably only needs to be expanded .5 mm or so, your millage may vary.

Nothing complicated to support here.
