Stereoscopic helper

It seems the culprit is the eye distance parameter + the unit setup in the scene (System units are in mm and Display units in cm).
Changing them both to centimetres and adjusting the eye distance parameter accordingly, i.e. to the default value of 6.5 cm, should resolve the crooked angle.
