A really simple, minimalist-style wallet!

Inspired by https://www.thingiverse.com/thing:2810337, but I disliked how hard it was to access the cards, especially any besides the outermost 2. So, I designed my own around fanning out the cards sideways!

The wallet works by having each corner of the cards be held in by a band on one side. It further has bumps in one of the corners on the long side, which can be lifted up to allow the cards to rotate outwards. This allows the cards to fan out while still being held with at least some force, letting you more easily access the inner cards. The bands also work very well to store a little money as well!
There may be some wear along the edges of the cards aligned with the notches, but I haven't noticed much at all in my couple months using it so far.

You will need 2 bands to use!
I used 2 hairbands, and they've held up well for a long time. Depending on your preferences, you can either arrange them to attach diagonal corners (as shown above) or in a connected 'V' shape. The notches for the bands should be large enough that they won't slip out nearly at all, but I like the 'V' shape since it keeps the bands attached to the cards even if they fall out of their notches. The diagonal attachment doesn't really prevent this, which is why I don't recommend it. It is more difficult to set up the 'V' shape, so see below for instructions!

There are 2 files; wallet_flipped is just the other file flipped across the y axis. You can download both, or just download one and then flip a copy in the slicer.

If you have any suggestions for improvements or problems with it, let me know!
