Male/Female Minimal Calibration Pieces

I worked out that the 'perimeter width test' from the reprap.org wiki only really tested for dimensional correctness in the x axis, and I wanted a test part where I could measure the sizes achieved in x and y for male and female holes. Circles are hard to detect error in just 1 axes, so a male and female 10mm 'plug and socket' arrangement is perfect!

Print this using your default settings, the male piece should measure right on 10mm in x and y and the female socket should also measure 10x10mm internally.
