Bed leveling tool for Prusa MK3 MK2 and s

This is simple bed level test tools for 210mm * 250mm of bed.
Test it with 0.2mm layer height it will not go over than 1st layer.

It starts from right top corner, prepare pencil and paper, write "Live Z" value for each row.

if the line shows empty space than you should consider down the value to negative.
Or the line collapse each other, give value positive, up the hotend bit.

Mine was best when Live Z value was at -1.170mm.
and shows that I need to up the bed left top corner a bit.
