This is version 3 of the Honda Odyssey phone holder I previously uploaded. This one uses about half the material than the previous version. It is designed for an iPhone 6/7/8 with a slim case (5.54x.34) and an iPhone X with a bulkier case (5.9x.48) but should fit phones between those sizes. It mounts between the steering column and the dashboard.
No supports needed.
