I had a lot of extra cards so i made this case
Step 1: What You Need.
a piece of cardboard (that is a thick or thicker than the usb.)
tape or glue ( i used tape)
Step 2: Cut the Cardboard and Trace the Usb Onto the Cardboard.
Cut the cardboard so that when covered with the card you can't see it. then trace the usb onto the card board.
Step 3: Cut the Cardboard Where the Head of the Usb Starts.
Cut the cardboard where the head of the usb starts.
Step 4: Tape of Glue the Carboard to the Playing Card.
Tape/glue the cardboard to the playing card then cut the playing card where the cardboard ends.
Step 5: Finish Up
Take the other half of the cardboard and glue/tape it to the part of the card that you cut off. Then place the second card onto the cardboard and cut it so that it matches the first card. Now place the two pieces of the card onto the cardboard so that it fits nicely with thew first card and your done.
