Z-Axis LS and Support

I wanted a better Z-Axis End Limit Switch adjustment mechanism and really didn't like the Acrylic Attachment bracket connecting the Z-Axis Threaded Rod to the X-Axis cross rail. The entire weight of the extruder, fang fan, and cross rail hung on 2 bolts that tried to break the Acrylic part in half.

The Tevo Manual shows the brass Z-Axis nut ABOVE the bracket, leaving everything hanging on those four little bolts. It's just a bad design. And the way you must fiddle with the Z-Axis Limit Switch is just insane. So I remixed [karthickrobo's](/thing:2575260) Z-Axis Nut Mount to include an adjustment wheel to vastly improve your ability to FINE TUNE the Z-Axis End Stop location. The limit Switch Bracket moves the switch to the correct placement.

The plunger is spring mounted so that any over-travel will cause the plunger to move up and NOT break the bracket or the switch. It's not a matter IF the carriage will not stop. It's a matter of WHEN. Hopefully, when the LS fails or t
