Fan Wallet

First model I've actually created, so I'm open to suggestions! I made everything in Tinkercad, as I found the program to be a good starting point for 3d modeling. ***NOTE: not for use with magstripe cards*** A fan-style wallet where you can open/close/eject cards with one hand, one card at a time. I have had my fair share of cascading wallets, and while I liked them, I was most attached to the Zeus wallet, a fan-style kickstarter wallet which I was fortunate enough to actually receive many years ago. Unfortunately the weight was a bit too hefty for me so I went to the drawing board to try to make something similar. A few iterations later, I ended up with this. Of note, magstripe cards shoudn't be used with this, as magnets and magstripes usually do not get along. A few notes about the design:-There is a difference between the middle card slots and the bottom ones. The middle slots do not have an area for the retaining ring to fit.-There is a small ramp at the end of the car
