The Slim Wallet

myminifactory

There is a newer version of this model available here http://www.thingiverse.com/thing:1756637. This print-in-place wallet holds up to five cards inside, prints standing upright and requires no supports. On the top side, there's a locking mechanism that moves down to lock and up to unlock. At the bottom, you'll find a lever to pull out the cards. After printing is complete, carefully remove the built-in support from the locking mechanism on top and then push the lever through its hole to help it release any stuck parts. This wallet requires precise tolerances.
