11-in-1 Calibration Block (Metric)

Calibration block in metric units. Contains 11 different 3D printer calibration tests. Model is solid so I recommend printing partial fill.
English units version: http://www.thingiverse.com/thing:217369

Be sure to print 1:1 scale so the tests are accurate! (Assuming your printer is sufficiently calibrated)

Tests:
horizontal and vertical hole diameters
3-axis feature minimum feature width test
scaling accuracy (via 10mm^3 cube cutout)
rounded feature minimum size
fillet m
