Just a little remix of Aeonfly's iPhoneX Case (https://www.prusaprinters.org/prints/47675-iphone-xxs-hullecase). This version allows you to design your own custom back plate. 

Since my starting point was an STL-file there may be a few imperfections, however they dont impact the functionality or the appearance of the outer case. 

The back plate has a thickness of 0.8mm. 

As an example i have included a multicolored fox-themed case that can be printed in the colors of your choice. This example comes as a 3mf file with the necesarry settings for PrusaSlicer incase you want to change the color combination of the parts. Additionally a gCode version is included if you want to get going ASAP.  

For more information on how to create your own designs i reccomend checking out “Make Anything's" video: 

I'm looking forward to seeing your designs!
