Compact Wallet Clipper

I was looking for a compact wallet clipper on thingiverse and couldn't find it.
I did not want something that could keep cash or something with some gimmick to make it longer than it should be.
I just wanted something simple and compact that could hold up to 8 credit card and nothing else.

Since I couldn't find it, I designed this item.

It's 13mm thick with the length and width of a credit card

Update from October 25 2019:
I made a V2 where I increased the thickness of the clipper by 1mm because it was too thin and it was breaking.
