This is a replacement for the back glass of the pixel 8 pro. My personal model was printed at .12 layer height in PETG. The couple of test prints I did were done with a layer height of .2 and still fit just as well.

While I've had my own pixel 8 pro I've gone through 2 back glass replacements even with a case on. The first shattered in a case after dropping less than a foot to the floor, the other broke when the lip of the case grabbed the edge of the glass when removing the case. Instead of replacing the glass with another piece of glass that would break, I modeled it and printed it in PETG. 

I plan to upload a version with a inlaid magsafe circle soon.
