@DocTrucker The Z-nuts are not adjustable on this design, maybe it looks that way with the metal by the endstop but that's only a spacer for it. Could someone help me to find some neat solution for partcooling? I've seen a design on Thingiverse that was made for the extrudermount that I have, but that was before I even considered getting one of those so I didn't save that and now I can't find it...
