Grips for 8bitdo's nes30 pro

I love this controller for my switch but my hands cramp up. Can’t find this anywhere, can someone make grips for this controller?

here’s a photo from a reference SL1500

I’m sure I could, would you just need the design or would you need it printed as well? Also, do you want it to have more of a playstation feel or XBox feel? I prefer the xbox but i have large hands. lol
