A Killflash designed to fit the Streamlight Protac Mount 1 and 2 weapon flash light.
 
I was inspired to make this after watching Garand Thumbs RECCE videos and it was brought to my attention the glare of weapon mounted lights. This was my solution and hopefully yours too.
 
There are some other Killflashes out there however I believe mine is made with superior quality and allows for more intuative "off" and "on" position. This also doesnt rely on a bungy system only friction, and when I compared it to some of my scope covers of similar applications, there really wasnt any comparison. 
 
Some back story and general information on the ATW Killflash. This is a 3D printed product made with a matte finished PLA, and extruded with .1 mm layer heights ensuring a higher durability and longevity. It's made on a K1 Max 3D printer and was painstakingly made over 250 times before I finally got to a point that I was confident in it's quality. Right now I have it in 2 filament colors being the Matte Black and Matte OD Green. I have tested both these filaments specifically to make sure they work with this design.
