Holosun 403 Killflash – 0.4 mm nozzle version

This design is specifically for a .4 nozzleIf you want to print a tighter hexagonal pattern with a .2 nozzle, use this model: https://makerworld.com/en/models/1030374#profileId-1013067Here is the design for the Holosun 503 Series: https://makerworld.com/en/models/1084808#profileId-1077415 This is a killflash/ARD (anti-reflective device) cover for the holosun 403B. It should work on other 403 series red dots, but i don't have any currently to test with. If you have one of these and it doesn't fit, let me know the dimensions and I can make the necessary changes. Works very well as both a cover and a ARD, while still allowing easy viewing of the red dot. It is just a friction fit, but once it is on, it is on there pretty snug.
