EDIT:
V2 (Black Wallet) has the following revisions:
The clip has been shortened, assembly now requires the bands to be wrapped around the clip in order to retain the cash better.
The sliding bands and the wide opening feature has been removed in favour of more secure band retention and extending the cards and pinching the wallet to fan them out.
The edges are rounded inside and out to allow for easy reinsertion of cards.
One of the plates has been given a hole to allow the clip to sit flat when no cash is being carried.

The following is for the original version (Grey Wallet):
Just print the two plates and one or two of the clips depending on your choosing, The only other thing you need is two hairbands, I used the silicone ones linked below as they grip the cash better.

The wallet also has the ability to open like a book to access your cards easier. It would also be a good idea to add something to the face of the clip in order to grip the cash better (I'm still experimenting with this).

When slicing in Sli3r, I changed the top and bottom fill pattern to Octagram Spiral to get a nice effect. That might be something worth looking at to customise your wallet.
