The ID of the Optical Snoot is 56.2 mm. No: it's not a perfect circle. There are 4 wide and shallow 'notches." From "notch" to "notch" is 57.4 mm. Also, the collar of the snoot is a soft rubber-like material that flexes and holds onto the Mini Flash 2.
The OD of the Mini Flash 2 is 55.3 and the far end and widens to 58.9 mm at the near end of the collar, which is 32.3 mm away from the end, with two thin "notches" along the way.

Do you have picture of the inside of the snoot?

I have progressed to trying to make my own optical snoot. I was wondering how the backscatter snoot deals with the focus light.
Because the focus light LEDs are not in line with the center of the snoot it causes the light pattern to look like this.
Are you able to see how the backscatter snoot deals with this? From what I can tell, It looks like there is a light diffuser right at the input side followed by the adjustable aperature card then right at the output of the snoot there is a lens.

There is indeed a lens, and when you have the smaller apertures in you get 2 little beams of light, that actually converge when you are at the "right" distance
