I've tried a BUNCH of different minimal wallet designs both printed and store-bought, and this is the best. It prints perfectly without supports and I didn't even need a brim. I slightly rounded the edges of the money clip with a file, but it's not necessary. I was a bit skeptical of the clip strength as the load is concentrated at the layer lines when printed vertically, but it feels pretty good in normal use so far in PLA. At first it is awkward to insert and remove cards, but after a few minutes of fiddling with it I'm fine. I use a strong card as the outer most, and slide it out a few cm while holding the jaw open just a bit. With the card out just a bit it holds the tension off the other cards and all is right with the world. It does take a minute to figure out. Another GREAT thing about this wallet is that the cards are incredibly secure. When you insert them the wallet lets you know with a forceful click as the jaw closes. I love the design.
