I designed this cell phone holder and when I upgraded my phone and also added a phone case, I needed to modify my holder to work with larger cases and deeper plug in. I'm using a magnetic plug for charging in for my iPhone 11 Plus and it uses a 90 degree swiveled connector and connects with easy. I created the back with grooves large enough for the cord to fit through with easy, just in case you were want to connect from the side, based on what some mobile have.
Update: v7 I dropped the front lip from 15mm to 7.5mm.
