We need to rotate the Rectangular Volume (object #4) by -90 degrees around Y axis; enter -90 for "Tilt About Y" parameter. According to the right-handed coordinate system, used consistently by ZEMAX, the negative rotation about the Y axis yields clock-wise rotation as seen from the +Y axis.

The "Z position" parameter for this object should also be (Outer R -5mm); set the following solve on the "Z position" parameter.
