A quick modification of my iPhone case into a case for a friend's Google Pixel1. Includes a tapered hole in the back for the fingerprint reader and a money/credit-card slot to hide things in the back.

Definitely for flexible filaments.

Only requires one support in the power plug hole, so I included one in the model that can be cut away after printing. (see red support in picture above) I wouldn't use any other supports.

I use "Simplify3D" for my slicer, and it has a great feature on the advanced tab called "Avoid crossing outline for travel movements". This keeps it from stringing thin filaments across the back of the case causing ugly scars. It instead moves around the boundaries leaving the middle clean. I highly recommend this feature. See the two pictures above that compare the travel paths (yellow) when this feature is off and on.

I didn't get to evaluate the fit much, so let me know if you find something that needs modified.

(v2): found and repaired flaw above power button.

(v3): added missing hole for earphones.

Infill doesn't matter.rnrnIf you haven't printed in Flex/TPU before, I recommend you spend some time reading up on it a little. There are several suggestions to make your prints more successful with flex filament. Printing slowly is one of the most important.
