Thin Wallet ID Visible w/clip

I was inspired by the Folding wallet cassette (http://www.thingiverse.com/thing:123670) which worked quite nicely for me, although it left some things to be desired:
-Not enough space for cards (in those days where everybody wants to put plastic in your wallet, you can't have enough)
-Not enough room for folded paper (Bank notes, german drivers licence) especially if there are some coins in the box as well.
For that I decided to remix this source instead of the original, since I liked the ID
