For a OnePlus 6 with the Otterbox Commuter case.
This is a phone holder I designed to go on the Proclip USA swivel in my car. It is a semi work in progress, I have not printed it myself yet but will be in the next few days.
Holes for screws are 30mm x 38mm to mount to a swivel. The Rear camera will work.
I am using this in combination with a dash mount I designed for a Miata at autocross events to for data logging using solostorm.

Adjusted size, the first print came out too large and the phone flopped around. Also adjusted camera hole for better alignment.
