This is my design of case for Pixel 3a. All corners are smaller so an impact is spread to case and not to a phone. Bottom speaker is redirected to the front. Case was printed with 0.3mm layer hight and PETG material. The notch on the opposite side from buttons is only for easer instalation of a phone to the case. There is small groove inside of the case to accomodate metal plate which I use for magnetic phone holder in my car.
