All Axes calibration

I was trying to print the large F4U plane from 3DlabPrint when i found that the pieces would not fit and after contacting support it turned out that my Z axes was 0.7 deg out of alignment meaning that my upright was tilting back.
I created this calibration piece that would test 150mm for X and 150mm for Y plus 100mm for Z then it would test the angles for X-Y, X-Z and Y-Z.
After printing simply check for the correct measurements and 90 deg angles then adjust your printer till corrected
