I wanted German Number Plates for my WRX (don't ask why, yes i know it's Japanese...). So I just held the body up to the screen and eyeballed it to get right size, printed it out (and yes I'm cheap) used clear packing tape cut to size so it's a few mm bigger than the plate and put it in the tub. It dosen't really look 3D since it's taped on, but I'm a noob; so I felt clever. Oh and I'll put some pictures soon, need batterys for the camera.
