I fixed the size and optimized it for cards measuring 86mm x 54mm. I use it to store several RFID cards that come in business card format.
Also I removed the side holders for the magnets and added a deeper square cutout (see V1 stl). If you prefer the round cutout from the original see V2 stl file.
