Clamshell bluetooth gaming telephone case design?

I really feel like I'm going loopy, searched in every single place and has nobody provide you with a slick design like this but? (apologies for the AI nature of the picture)

You would have the telephone case higher part bought individually to match your telephone mannequin after which clip it onto the ridged hinge of the bluetooth controller making it a clamshell case. Don't plan on gaming at present? simply unclip the controller on the hinge and you’ve got an everyday telephone case.

For the reason that controller width wouldn't be capable of match each telephone measurement; have it designed barely smaller than most telephones and together with the acquisition of the telephone case you get a rubber bumper to snap across the fringe of controller to match the width/peak of the telephone case (the thumbsticks would additionally must be recessed or DS type)
