Closeable Business Card Holder

This is a simple closable business card holder. Holds many standard 3.5"x2" business cards. It can be closed up and put in your pocket and taken with you.

You will need to pass a piece of filament through the holes and then use heat or glue to stick it to either the base or lid, but not both. I recommend fixing it into the lid. The inside of the lid will need support.
