Card Wallet (modular)

I am a man who travels without cash. I always carry my cards and maybe a banknote. I have been using a printed wallet for a while now, as it is part of my hobby.I wanted something modern and something fresh. I thought about a print and place version, but it is not what I wanted.I started to forge a plan in my head, then put it on paper, and finally let's go draw :) 6 cards go in the wallet and cash in the drawer at the back, but if you double the wallet you can have 12 cards or a combination with drawer.Everything is modular and can be assembled at you wish. For the basic model you need 6x Hex M3x12 screws and 6x M3 nuts, for the extended version you need 6x Hex M3x20 screws and 6x M3 nuts. Basic model extended version
