20mm Cube for Calibration

thingiverse

This is a calibration cube designed in OpenSCAD. The letters should stand at 12mm tall and 11mm wide when measured correctly. The cube itself, as indicated by its title, should measure 20mm along each dimension. When printing with layer heights less than 100%, remember that your z-measurement should be shorter than 20mm by the amount of layer height plus (layer height times first layer percentage divided by 100). Also note that if you print this cube in layer heights which are not exact divisions of 1mm, then the letter heights may not be precise. The letters should appear centered on the face they are printed on, both horizontally and vertically.
