This is a pair of inserts to go in the central console of a Tesla S or X. It fits my iPhone 6 in its protective case. It may need adjusting for different sized phone cases.
I made an improved version, which is the 2nd file. This is just the left side, but you can mirror it in Cura etc to make the right side, after adjusting it to fit your phone..
