Version 2 (more like 5.2) now with thinner grid at 0.4mm thickness!

Including the Fusion 360 file!

Whether in airsoft or out in the woods, shiny stuff is really easy to spot. The front of your flashlight is a large perfectly reflective device. Adding an ARD can greatly reduce the angle at which the shiny mirror surface can be seen by anyone viewing your location. 

The cap can also be used to ensure even accidental button presses won't reveal your location.

This is similar to ARD caps put on scopes or other aiming devices. Fusion 360 file now included to provide you with more options to get your perfect fit.

Ensure you measure both your flashlight (or other item) front end and ensure proper clearance for good fit. 

I used 1/8" inch Shock Paracord to string through to ensure a secure retention of both the ARD and cap.
