Well I decided to use the same bit for joysticks, it worked out fine, plenty of play and the dust covers cover the holes.
The center button on top is going to be a "pause" button, I forgot to order a yellow illuminated button for that. I will swap it out when it gets in.
I'm not incredibly happy with how the "brushed aluminum" vinyl looks on the CP, I will probably change it to black in the future.
Pretty tight fit, but I got creative to make it work. I'm getting impatient as I started this project a while ago, perfect is taking a back seat to quick these days.
Not exactly award winning, but I don't think it looks terrible.
