Ergonomic XBOX Controller Grip

I am an above average height man and my xbox controller makes my fingers cramp after about an hour of play time. To combat this I used a scale model of an XBOX controller that I made (on profile page) and another scan of a mold of my grip. This is the outcome. I hope if anyone has a similar issue that you will try this invention out :). Support me if you think this is worthwhile. (Once attached as you please, it will make your controller stand freely.)

Make this with PETG so you can do some light sanding when you're done for a better grip.
