X and Y calibration model

I was experiencing very strong astigmatism on my printer (circles coming out as ovals) regardless that square or rectangular shapes were coming out totally fine. So here is a quick calibration model combining both types of shapes I came out with in order to solve the problem with M92 adjustments.

Original dimensions :
- Circle
. Outer diameter 140.00 mm
. Inner diameter 136.00 mm
. Thickness 1.00 mm
- Cross
. Length in X
