I think only akai will have the "cad" .
I went to a graphics shop today and they can make the skin once they have the "cad" , (same as you),
So I typed in cad makers and there are a few about, there is a bloke about about 30 miles away, I haven't contacted him yet, he charges £40 hour, I have no idea how long it takes to make a cad.
Are there any cad makers near you? You should get your money back as and when you sell them.
Also if you had the only cad copy then you could sell it on.
Let me know what your thinking, as I would really like one,
