Flashlight mount for airsoft, nerf, or even real steel firearms if you're willing. Uses two releasable zip-ties and one 21mm flashlight (on Amazon here). This would be very easy to model to fit a different size flashlight with your choice of software, if you request it I might add more sizes. Used this on my Zinc 2.0 and it is very stable and slides on with ease.
