Adjustable, elevated y-rod holder for Mendelmax

Inspired by Michael521's great hidden-electronics conversion kit idea (thing 18044), I set out to to the same thing on the slightly oversized Mendelmax variant that I am building. These y-rod holders are made for 8mm y rods. They include a hole for small screw and a slot for a trapped nut that together, act as a clamp although in practice, clamping doesn't seem necessary. The outside facing part of the holder has a channel allowing the use of a screw and washer to tighten it to a trapped nut
