Fiber optic ring light adapter/mount for light source

1/4-20 threads for a set screw and I sized up 2% in my slicer for a slip fit and 1% for a snug fit. The threads work best if you have a tap to chase them but just using a screwdriver to run in a 1/4-20 bolt works just fine. Holes are 1/8 inch for mounting onto light source of your choosing.
