This case and all of the modules that i have designed so far feature polypanels (at 0.88 scale - adaptor piece pictured also). The case itself is a remix from thingiverse' ask4help- simple galaxy S7 case that i have added a back plate to. This case is fully customizable - with polypanels anything is possible.
