Phone holder for 2011 F-250

This was designed to fit a 2011 F-250, but should fit a wide year range of F series trucks. For reference, the base measures 2.5"x4.61" (63.7mmx117.25mm) and the phone holder area measures 3.19"x5.69" (81mmx144.5). It fits my iPhone 8 with a thin spigen case pretty well

Note this is my first 3d design so I bet there were better ways to make this, I would appreciate any tips/tricks/advice to make this design better.
