Print this, measure diag both ways, calculate skew, compensate in firmware, print again. 2 models here if you have mag plate, print the one with 4 parts and pull bed plate off, measure, check. Compute AB : SQRT(2*AC*AC+2*BD*BD-4*AD*AD)/2 XY_SKEW_FACTOR : TAN(PI/2-ACOS((AC*AC-AB*AB-AD*AD)/(2*AB*AD))) https://www.klipper3d.org/Skew_Correction.html https://marlinfw.org/docs/gcode/M852.html
