Thin SIM holder

I travel a lot, and I have a few SIMs between my phone and its case. They were flopping around and loose, so I decided to print a holder for them. I didn't want the holder to increase the thickness, though, so I made it exactly as thick at the cards.

On my Bambu P1S, the cards fit exactly in the case, and stay in place press-fit. If your printer has different tolerances, you can scale the model up or down, respectively.

Here's a link to the OnShape source, if you want to remix things or change the number of SIM slots you want the holder to have. If someone wants to, I can upload holders with different numbers of slots.
