I added some eyelets for running some string through to keep the killflash in place. I received some good advice to try and make it so it is easily removed and not permanently affixed to my scope. My scope is 35mm so I scaled it down for mine, but I included the original size of 45mm. I have a resin printer so I also included my supports file for anyone who is interested.

*I used a thin strip of bicycle tire rubber I cut to go in-between the print and the scope and scaled the size of these models to allow for clearance of the rubber.
