AM8 MGN12 z-axis / extended x-axis 300 buildplate

Modified AM8 and AM8 2020 x-axis parts. 400mm MGN12 rails used for z-axis. Relocated z-motor position for extended travel of the x-axis. Not entirely sure if a 300x300 bed will fit due to actual bed size measuring 310mm but a 300mm glass will definitely fit. Removal of 2040 z-axis supports may be necessary.

Included both normal size x mounts and anti backlash size mounts. Print the x-axis with supports on.

1 side of parts is included. Just mirror the part in your slicer for opposite side.

Added x-motor mount, x-endstop, z-endstop, z-endstop stop. Endstops are for ramps 1.4.

Re-worked the design of the XZ mounts. Found once mounted they were not strong enough. Had some flexing in the z direction. New ones don't flex at all. I suggest printing these XZ mounts with 100% infill.
