Micro Wallet

thingiverse

A tiny wallet that can hold on to your cards. Designed to lock into place to secure your cards, and to unlock so you can easily peruse your cards. It behaves much like an elastic band wallet. You need to customize it for the amount of cards you carry. Simply stack all of your cards together and measure the thickness of the stack. Then open the customizer and set the inner_thickness of your wallet and you're ready to print!
