I couldn't find a proper Google Pixel 4a 3d model anywhere with correct side profile, a few models I managed to find were completely wrong, that's why I decided to make one myself from images and real life measurements.
This model isn't supposed to be printed, but used as a tool to design cases or other accessories easier. Fusion 360 design file is attached so feel free to create amazing things with it :)
If you don't want to design your own case you can try mine: https://www.printables.com/model/431525-google-pixel-4a-4g-case
