This wall holder is designed for the Google Pixel 3a XL, especially using the official Google fabric case. There are two versions included - one with a notch that allows you to dock or remove the phone with the USB cable attached, and one without the notch.

Edit: July 31, 2021 - I added a shorter version that allows access to the volume controls and fingerprint reader and also has a wider front opening which doesn't cover the screen at all. This is probably the version you want...

The best way to print this is with the back flat on the bed, with supports. Infill isn't very important.

You may wish to consider printing at 101% width to give a little extra wiggle room on the sides of the phone.
