World's Smoothest XYZ Calibration Cube (G3 Curves)

World's Smoothest XYZ Calibration Cube (G3 Continuity)

This is an XYZ calibration cube to test the smoothness of specular transitions between 3D-printed perpendicular flat surfaces with a G3-continuous fillet, as found in many Apple products. It works best with a high-gloss material, such as Silver or Silk PLA, so you can use a bright light source to clearly observe specular reflections.
