Ví mỏng tối giản (Slim Minimalist Wallet)

I wanted a slim, minimalist wallet for a long time. The two main issues I found with several of the wallets I tried were that:

1. They were either designed with specific number of cards in mind (or one had to print variations every time one needed to add or remove a cards), or

2. That they relied heavily on the elastic rubber bands as the barrier to prevent the cards from sliding from some of the sides. This made the rubber bands rub against the cards, making it hard to grab cards out or put them in and needing frequent replacements of the rubber bands.

This design resolves both of these.

Print two of the model with the face down. If you have a print bed with a pattern, you can use that to give it some flair. Do not apply mirroring to either part! Face the two sides against each other and use one or two elastic, rubber, or hair bands to hold them together.

I have tested this with 1 to 9 cards, and the tabs at the bottom and side will hold the cards and prevent the bands from interfering with using the cards. Although I don't recommend it, it is possible to use with more cards, but at that point one is relying on the strength of the bands to prevent the cards in the middle from sliding out. If you use more than 5 cards, I'd recommend using at least two bands. Personally, I've found 2-6 cards to be ideal.
