Pixel 6a case thick back

This is a remix of @kokopopsthepops Pixel 6A phone case. Really good case. I just increased the back thickness by 1mm to help protect the glass covering the rear cameras and flash and probably some other sensors from scratches and other damage.

I'd recommend melting the edges near the USBC port as the filament cracked linearly along the layering causing the corner pieces to break off. This is just a weakness from the printing process.

Version 2: increases the thickness slightly for more clearance.
