SAE LM6UU Huxley X Ends

I have found that the Home Depot sourced 10-24 nuts and 4-40 nuts are poor replacements for M5 and M3, respectfully. I have enlarged the nut traps and the z anti-lash fittings to better fit these sizes. I am uploading this to give proper respect to the work done before me on these amazing parts, as well as to possibly help others finding themselves in the same situation.

I also added a beefy z endstop adjustment holder, because I wanted a beefier looking one than the ones I have seen upload
