Iphone Dash Display

Hello! This is my first upload, so please be kind. I wanted to design a case to mount on the dash of my truck that would feel like it was at home in my favorite sci-fi movie, and would also allow me to use it like a dash cam, as well as with apps like Spyglass. It is designed to hold an iphone 5. The screw holes on the case are M2, and the two downward ones are M5. I think it should print pretty well without many supports. Sadly I have no printer, so for now this is only a digital project.
Please let me know if you try printing it, and I apologize in advance if it doesn't work or fit, as this is my first big design.
