Storage and hat Clips for LED flashlight

Storage clip for LED Flashlight. My local hardware store has these cheap LED flashlights by the cash register. I have a bunch and needed a place to store them. The center shaft is 25mm in diameter, so this could be used for other items of similar diameter.

While fixing something at home I needed to hold the flashlight while working. I immediately thought about changing the clip to hold it on my hat. The grippy teeth are inspired by http://www.thingiverse.com/thing:13612 .
