A woman contacted me, explaining that the latest version of the Playstation controller was almost unusable for her. The triggers were not working as she played in the top-down style, where you put your hands on top of the controller and use a surface to grip the triggers.
Initially I was going to design some kind of grip that glued onto the triggers. Then, I came up with this idea.
It isn’t perfect. It may not even solve her problem (ps4 triggers are at a different angle. not much I can do about that). however, it exists now and maybe it will help others.
This mat was printed with Ninjaflex on a Lulzbot Taz4 3D printer. This means it is a flexible rubber that grips the surface below pretty well. You could really use any soft rubber for this, I suspect that a rubber/gel insole might be perfect actually!
