8 Card Wallet

This is a wallet with a money clip, and a slot for a [USB flash drive] [1].

Other than the obvious wallet-y features, the design goals here were:
- Cover the cards as much as possible, to avoid damaging their edges
- Hold a USB drive, to let me remove the one I was carrying on my keychain
- Avoid sharp edges, which were apparently abrading holes in my pockets

Known flaws, after carrying it around for a bit:
- The money clip's clearance against the wallet body is too loose, single bills don't clip well
- The money clip spline's nearest point to the wallet body is too far out, folded US currency doesn't sit flush against the spine while under the clip
- The radiuses along the edges of the piece create a thin wall that eventually split. I'll redesign this and address this issue in the next version.
