This would be such a great thing to make, if I had a dremel tool… Still, if you aren’t crafty, Rachel has many novelty USB keys for sale, too! 
This could be the solution to my desire for all things novelty USB. Everytime I see a new USB key shaped like food, or animals, or Jerry Garcia (ok I made that one up) I covet it to the extreme, but usually they are cost-prohibitive. Besides paying for the key, you have to pay for the cutesy container. If you can find a deal on the USB key, and then go to the dollar store and find a Hot Wheels car or a novelty keychain, it could be cheaper, and certainly more rewarding to build your own!
