Stereo microscope light ring using neopixel LEDs

The idea started from https://www.thingiverse.com/thing:2331410 but:
I am using a 0.5x lens to lower the magnification
In preliminary tests my opinion was that the light from only one ring is not enough and I used two adafruit neopixel rings .

So I designed a new system of fixing in the channel of the 0.5X lens and modified the LED casing. Now it is a two part system one is on the lens made in black PLA and another one is the case for Neopixel LED rings printed in clear PLA used also for light dispersion
