Pocket Hanger
Description
Attach to your keychain, hang on the inside of your pocket, and your keys will disappear. You won't feel your keys resting at the bottom of your pockets any more. Once you try it, you won't go back. :)
Instructions
I added a second file that has a bigger hole for your keychain.

A really good thing, and a great example of how 3D printers can create genuinely useful tools. I've made it my Thing of the Week on 3Dgeni.us - check it out!
Really glad you enjoyed it. It was an invention of my father's.
