Not me, I hate waiting.
You motivated me, so I am finishing up the new z nut lock now, that will pretty much finish up that assembly. Print parts tomorrow. Pretty happy with it if it works! Difference hardware wise is no more 1.75″ or 3″ bolts and 5 3.5″ bolts instead, 1 screw and nut for the z nut lock and it is trapped on the bottom instead of the top, easily tightened or swapped out!
Then work on the z motor mount.
