Z-Stop for solidoodle modified to use a M3 nut so loctite blue will work better between the nut and the z screw. Prevents vibration from making the Z setting change (or helps prevent it, anyway).
I've now updated the files with the v2 version that provides more support for the nut (because the nut popped out of my original :-).
I needed a really short version, which led to the v3 files. This version makes sure the mounting bolt heads will fit even if they might otherwise intersect the bar holding the z screw.
