Look at the first shot in this stereoscopic cubic illusion of a cube with a 33 degree horizontal field of view (hFOV).
Move progressively closer to the image for the following shots to match the hFOV amounts that are needed to squeeze the depth of the cube back into a cubic illusion.
Not coincidentally, 4.4% NetD requires a 44 deg hFOV, 5.5% NetD requires a 55 deg hFOV, etc. Our human binocular hFOV is limited to about 100 degrees, so the final shot will require getting close enough to the image to fill up our entire hFOV.
3.3% (1/30) Stereoscopic Net Deviation is the only amount of depth that can produce a perfectly cubic stereoscopic illusion, viewable with any horizontal field of view (from any seat).
