CMF phone pinball

A pinball case I made for the CMF phone 1. I used one of the balls from the ball bearing of an old fidget spinner I had lying around, but you can use any ball you like as long as it has a maximum diameter of 4mm. Sorry in advance for any hasty design flaws, we're going on holiday and my parents are literally screaming at me that we have to leave while I'm typing this:( Enjoy your pinball phone case!
