I'm looking to perhaps design some cases using some of the photography from projects that I will be doing (hopefully make a bit of cash from them, as it would be a great little source of income), but have no idea how to go about it. I have no need for fancy shapes. Just a basic shape that leaves all the holes uncovered that are needed (camera, 3.5mm port, charging port, noise-cancelling mic, etc), and that's it. Any idea where I can go to start on this?
