This is a remix of jfeist's Pixel2 case with bumps on the side to make it easier to hold, and a space for the metal plate for my magnetic car mount, and a stand to slip the charge cord in.
I also included the first version of the stand using my old charger cord from my Nexus 6P, end is 6.5mm x 12.2mm x 20.25mm (one for home, one for work).

I printed at 0.1 to reduce the step look on the 45° slope for the stand.
You need to have a well calibrated printer to make sure everything fits properly. I had to print the case 3 times to get it right (1st time was pre-calibration and came out too loose).
