Combination Lock USB Flash drive Case

This design came as a result of difficulties on using my flash drive with built in security software on university PC's. The network just would not let me use my memory stick rendering it not particularly useful. As a result i set about designing a fun combination locking usb case with the advantage of being able to set your own 4 digit security number. * The actual flash memory is not supplied (purchased at www.rapidonline.com) just the combination locking case* Check out my original post......http://www.instructables.com/id/Combination-Lock-USB-Memory-Stick/
