The neutral plane for creating drafts

The next step is to apply drafts on all faces. Its important to consider the location of the neutral plane, that is, the plane which the face is "rotated" around. If we choose as neutral plane the bottom of the holder, then we will have a problem with the wall thickness in the top part of the holder. Therefore, we create a datum plane at an offset of 40mm from the XZ plane as a compromise between the top of the holder becoming to thin and the bottom becoming to wide.
