About this 3D model

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 minimum size Vertical and horizontal max tower height to diameter ratio Max build hangover angle test (30 - 80 degrees) minimum layer thickness Bug fixes: Fixed text order on some of the labels. added a horizontal pillar protrusion test. Yes, that makes it 12 now. lengthened the minimum layer height test.
