Card holder

Compact design to fold your cards. With these dimensions it can hold up to 8-10 cards, depending on the type of card, of course.
It's been designed to be printed using an elastic plastic for the middle part, in order to make easier to take cards in and out and making still a pretty good enclosure (I never was able to take out the cards by shaking it, with a reasonable force). I also used M2 Screws to make things as small as possible.
Enjoy it! :)
