Level check Da vinci Junior

This was developed with the XYZ Da Vinci Junior in mind

This is a simple testpiece to check:
1) if the bed is level
2) adhesion to the bed

I print this after:
a) X-axis calibration to check the even level of the bed
b) check the adhesion to the bed after Z-offset changes

After printing you can check:
a) If the bed level is correct the thickness should be the same all around the part
If this is not the case: calibrate X-axis

b) if the adhesions to the bed is ok, it should be stuck same all around the part
If this is not the case all around: calibrate X-axis
If it is not sticking in general: correct Z-offset
