this customizer generates a hex grid wrapped in a tube with optional lens wrench notches, to be used as an ARD (anti-reflection device) or "killflash" for scopes, binoculars, and other optics. the center hex cell is zeroed to the tube axis for all configurations to avoid obstructing your sight. the default settings and stl file fit a pa 2x cqb-m5.

there is a boolean toggle that changes "diameter" to specify either the internal diameter or the external diameter of your scope, and the opposite diameter is calculated from the specified wall thickness. this way you can easily choose either a slip-on or press-in design.

install the grid side outward to avoid grid contact with your objective lens. extend the tube for greater standoff or retention. slip-on tubes should generally be longer.

this is my first design! please leave feedback :)
