The strange orientation of the upper interstage truss

After some further checking, the interstage truss is actually correct.
It turns out the bottom of the third stage is wider than the top of the second stage.
Therefore the truss should be placed so it is wider at the top.

Cutting out the truss for the second stage.
there are for layers glued together for strength, two layers of card with a layer of printer paper on each side.

Truss between the second stage and the third.

There seems to be a mistake here; the white attachments for half of the attachment points are meant to match the third stage which is white on half.
However, the white pads are on the larger circumference which would logically put them against the second stage (unless you install it upside down, which does not seem right at all)
