P3steel 2.x toolson X-Axis 1.1 endstop mount remix

toolson's excellent design but ~2, 3 and 4 mm farther away from the x-axis rods, since I ran into minor hiccups with the original version, the GT2 belt and the M3x6 screws I used.

The 3mm version works best for me but YMMV, so choose the one that works for you.
