The origami weaving model has progressed since the last posting.
Now I have the first intermediate strands locked into place. They look good.
I am not entirely sure about the method of connecting the second set of intermediate strands. I have one in place. (See the back view). I may have to redesign the lock if it remains able to slide down its connecting channel a little.
I have discovered that the model is easier to assemble if I leave the lock squares on the main strands unfolded until they are assembled with cross piece. The blue strip poking out the top is longer than its neighbour purely because the visible pre-creased squares have not yet folded up.
The smaller end sections are lock folded in place so that I don't lose the pieces. They unfold relatively easily with a little gentle care. Forcing them can mangle, crumple or tear the paper.
