Simple Credit Card Holder Free 3D print model

I need a holder for my cards that provides secure protection without taking up too much space, but I'm uncertain how many cards will be inside, so I've created one that relies on a rubber band to keep them in place. A crucial aspect of the design just failed; the top section has already snapped off after some usage. Given that it's printed horizontally, there is limited structural support at the top, which contributed to its failure. To fix this issue, I'll need to revamp the design.
