Noctigon KR1/KR4 Tactical Ring (18650 version)

thingiverse

This is a tactical ring for the Noctigon KR1/KR4 flashlight with 18**6**50 battery tube. _18**3**50 version is available [here](https://www.thingiverse.com/thing:4709923)_. It replaces the clip or lanyard ring. Assembly is easy: Screw off the tailcap, remove both o-rings and the original clip / lanyard ring, “screw” on the tactical ring and gently but firmly press it down. Install the thick o-ring – and only the thick o-ring – and screw on the tailcap. If the light does not turn on, take everything apart and scratch off some material from the inner ring (front side). The inside requires supports. Make sure that the thickness of the inner ring is exactly as in the STL, otherwise it won't fit. I have included a second version with integrated supports that should work fine. Print with 0.1 mm layer height for better quality.
