Remix of Ender3/CR10 ZBracket, thicker and reinforced a bit

Just wanted a beefier z-bracket.

Also created a gcode file that takes the Z axis up to 235 then re-homes Z axis (over and over) so you can home in the center of the z-rod by moving the motor. Check the center/alignment of the Z-rod as the gantry is raised up and down. Position the motor so that the Z-rod is centered/aligned (or as close as you can get) when the gantry is at the top and bottom.

Cancel the print once you have centered/aligned the z-rod
