Cell Phone Charger Clamp

I wanted something to hold my cell phone charger/stand to the headboard of the bed. This design appeals to me because it uses a compliant spring to hold the charger in place.

This thing will be useful to exactly 0.0 (repeating, of course) people. I just wanted to share this because designs like this show how 3D printing can be used to create useful things that have no commercial value but can be useful to someone.
