Cad file of R53 Mini dash board

I am trying to create a cad model of the dash top of my automobile and R53 2002 Mini Cooper. I need it to allow myself to 3D print a device. I lack scan ability as I do not own an iPad and I am not very tech savvy any ideas…

Since you have the car, you could take measurements of the dash to use in modeling it. What is it you are planning to 3D print? Do you need the entire dash top modeled or just a portion of it?
