Done!
Car Door Speaker Enclosure collection - Thingiverse
@DocG - I'm in Australia, I don't think you want to pay the postage from here to get a set from me, and I'm not really looking to make money off these things anyway.
But it looks like if you go somewhere like here -
https://www.3dhubs.com/boston - should be able to print it off for you. You just need to grab the STL files from Thingiverse and you're off to the races...
