Here is how it all went down
Dremil with circular disc + thing long tubular sander attatchment
long nose pliars
Crazy glue.. (good quality stuff otherwise it turns white, used bostik)
thin tip marker
1) remove center piece (no need to remove upper peice)
2) remove two screws holding cup into place, cup then pops off. (see red arrows on pic)
3) take one of the controller extensions and place it underneath the cup and mark the outside, remember to mark the smallest part of the edge not the widest, so you have something to stop it from going all the way through and something to glue to the cup
4) Mark a second, its gonna be pretty close as you will notice .Take into consideration the thickness of the blade that will cut it..
5)once marked, cut very carefully, use the long nose pliars to remove pieces gently...
6)Use the second dremil tool, the thin sander piece to smooth edges and corners...
7)Lastly glue into place,the controller port should stop half way do to the wider peice, then you know you did it right when you push it through the hole... let sit for about an hour...Run your wires neatly to wherever your entertainment unit is located...Youre done
The cup still functions yet wows your friends when you whip out the entertainment system...
