It would be cool to put the phone upright in an extension of this tray to show the gauges so my friend did this 3d model that allows this! He says that the model has fiction fit for a phone with case that measures: 151 x 75 x 13 mm. Printing should be with automatic supports and brims.
I have an iPhone 15 pro with a Spigen clear case, for example.
I recommend a cigarette charger for when one needs a cable charge. The iPhone needs to be flipped so as to position the camera away from the tray lips.
