There ya go! My original attempt was sawing off a old unused aluminum camera tripod leg that happened to be the correct diameter. Then ground it to size on a belt sander then a diamond stone. Very difficult to get precisely parallel edged plus kind of hot on fingers.
If machined correctly, reamed, outside turned and reamed to close tolerances then cut to the precise thickness, I don't see a need for set screws, at least on my Ziess (don't know about the NXS).
Thus there should be no warranty issues.
LR, we'll let you take the lead on this one.
I don't know if its cost effective but project like this are very satisfying.
