So I'm going to get the ZN-40 case most likely, and I want to be able to get trigger buttons on the back, most likely from a ps1 controller which would be two z buttons and the left and right bumpers. So I would need an area that is wide enough to hold those buttons on the back, but I don't think the plastic is wide enough, is their any way I could make it wider because I have seen other people with the same case who have made it wider. So I might have just come up with a solution that might work, by taking the ps1 controller and maybe dremeling off a piece of where the trigger is, sanding it down, and gluing that onto the case. not sure how that would look though.
I want it to look like this.
when originally the case looks like this.
