Mobile Phone controller grip (with trigger inserts)

Mobile Gaming Controller for Iphone X with Trigger inserts.
This is a project that I got into when Fortnite came out on mobile. All of my friends played it on a console and I wanted to be a part of it as well. I saw the gaming cooling grip on Thingiverse and printed that, (scaled up for my iPhone X of course) and played like that for a while. after seeing some triggers for PUBG I quickly ordered a pair for myself but i couldn't use them with the controler so I used a grinder to bore out a spot
