Minimalist Oval Wallet

I have been looking for an easy to print minimal wallet for a while now and I could never find one that was strong enough and didn't use a ton of supports for a reliable print. So I decided to design my own, the walls on this wallet are about 3mm thick all the way around for strength. I tried to design this wallet to use as little support as possible although I still had to manually add supports in Simplify 3D.

Holds: 8-9 cards or 8 cards and a folded bill as shown
Orientation: Print vertica
