Openscad and STL file for printing a phone case for your new Google Pixel 3a.

I have added an updated STL and SCAD file for PLA printing.
The new design is thinner, allowing for non-flexibles to be used.
It also has larger cutouts for the headphone, usb, and side switches.

The new files are:

pixel3a_case_final.scad
pixel3a_case_final.stl

Print instructions

Recommend using flexible filament such as Ninjatek Armadillo.
Print without support and trim any overhang errors.
The pixel3a_case_final files can be printed with PLA or similar rigid materials.
