Prusa Mini Z-axis dual beam brace

This is a REMIX of the Z-axis brace by Fada, where it is enhanced by removing the very sharp mounting hole and moving one of the beams out further in an attempt to stuffen the Z-axis more in one direction and adding another beam in the other direction. Also, change the juncture and mounting holes to where they ALL come together to make a more robust looking and functional brace.
