I am a fan of minimalist design, and a wallet was a simple project that would allow me to exercise my design skills. The wallet, which can be found on Thingiverse.com, features a quick access card slot, a slot for the rest of your cards and elastic band that work to hold cash or business cards.
New part files are available! The parts can be downloaded here or from thingiverse. This new version has more curved edges to allow for more comfortable use and better movement. If you do print a copy, please post some pictures to the thingiverse page.
