SnapMaker Z Spacer Block

I am replacing the electronics on my SnapMaker 3D printer with a RADDS board and upgrading the extruder to a Titan Extruder. In the process I realized that it would be considerably easier if the Z access was flipped so that it has a Z Max Endstop instead of a Z Min Endstop. In order to do this and not loose a large amount of the build volume I made this spacer that will go at the bottom.

Requires 4x 60mm M4 bolts to attach the Z Axis to the base plate.
