I'm a fan of Fenix flashlights, and have a number of them, with various diffuser lenses, etc. The only thing I'm not happy about is that their lights can't tailstand on their own. I created this small holder for my LD-22 flashlight so that it will stand up on its own. It's just a bit larger than the light's diameter, so the light can be pushed down onto the nubbin at the bottom to turn it on and off without removing it from the stand.
