Nintendo Switch JoyCon grip for iPhone 15 Pro Max

This is a frame for attaching JoyCons to an iPhone 15 Pro Max.

I print it with the backside on the print surface with supports only in the rails.  

My model is based on these joy con rails: https://www.printables.com/de/model/979097-joycon-rails

Updated Version V2:

• The phone fits now a bit tighter
