Iphone 5 inspired Xs max bumper case

I was really fond of some leaks before the release of the phone when it was rumored to have stainless steel housing like the older iPhones so I ended up attempting this design. I tried 3D printing this but the wall of the bumper was too thin and would be easily deformed. The idea was to make a thin bumper case that, with a screen protector, would make for a flush fit. However, even at the current dimension, the phone with the bumper installed is quite chunky and not as portable. I would love to make the same case for Iphone X or Xs to see if the form factor is more ergonomic, but sadly I do not have those phones at hand. If you attempt to do a similar project for smaller iPhones, I would love to know the results.
