A squaring block for the MPCNC IE Edition

This is a simple solution to achieve more rigidity and better squaring between the X and Y axis for Allted's MPCNC IE. I think it will work also for the normal version but I'm not sure.
Print it horizontally with a infill of 50% or more and a skin not less than 1.2 mm. Be prepared for a 10 to 12 hours printing.
