This is an updated version of the Mixbox style controller that I posted a while ago. I redesigned it to be slightly wider, as well as designing a sliding lid to remove the need for magnets. I found my hands to be slightly too large for the original version after extended use, but can confidently say that making it slightly wider has made the controller more comfortable to use. There is an optional file for an 8BitDo phone mount (slide the bottom lid out halfway, 8bitdo phone mount slides on over the feet on the bottom, then close the lid once it is on)
This is the 8BitDo product that I used to hold the phone onto the mount.
