pinephone back case thickened

This is the back case of the pine phone keyboard with all of the keyboard features removed.
I originally had issues 3d printing the stock case back because of how thin it is so i modified it to make it printable.
changes made from stock file:
thickened by 1mm
cutouts added for ports
pins thickened by .5mm
speaker holes redesigned
back made flat
mic hole made bigger
power/ volume buttons made bigger
