Not happy with the metal versions (they scratch anything else in my pocket), I decided to design and print my own wallet.  Myself and one of my best friends have been using this wallet for many years now and haven't even needed to replace the band (you will likely need to if you thin out your cards by a significant amount).

This is super cheap and easy to make - the last wallet you'll even want/need!

I typically print it in ABS for durability.

The band is a XL “ranger” band from Amazon - [https://smile.amazon.com/dp/B08MVHWY6X](https://smile.amazon.com/dp/B08MVHWY6X)

3.5" x .75" bands ($9.49 as of 04/2022, 15 count, so you have replacements or can make a bunch of these).

There's a "bump out" on one side to hold cash better. There are slight bevels on each side to more easily insert cards.  I typically gently sand these down so they are smooth and have no layer lines that might cause cards to catch.
