There aren't a lot of R53 Mini Coopers on the road these days, and even fewer with the DVD navigation system, but if you have one you're probably staring at the semi-obsolete computer screen (my nav's been broken for years) and wishing you could get your phone there!
This tray fits an iPhone max with a massive case, and there's a removable insert for my smaller Samsung S21 case. The .scad source is included so you can make other size inserts or adjustments.
The 3 small “wedge” pieces slide between the frame and the screen, locking the bracket in place. Assembly is shown in the rendered image.
Given that this is going to be in a car, you probably want to use PETG or ABS/ASA – PLA will melt on a hot sunny day.
The author marked this model as their own original creation.
