I made this some time ago, I use it daily.
You just slide the dock in the space in front of the gear lever, attach a cable (I used an old OnePlus USB-C cable) and connect your phone.
You need to modify the width of the dock, it varies from phone to phone.
You can also adjust the position of the connector (up or down).
There is a small screw hole if you need to lock the connector, my printed part just stays in place so I didn't need it.
Enjoy.
