Open one hint at a time to preserve some of the challenge.

Hint 1

Lay out the nine pieces using the labels A1, A2, B1, C1 and D1–D5 from the diagram.

Hint 2

A1 and A2 create the starting frame; B1 crosses it to make the central core.

Hint 3

The D pieces are added one at a time, with D5 acting as the final key.

Join A1 and A2 to create the open starting frame.
Cross B1 through that frame and rotate the three pieces into the central shape shown at stage 4.
Add D1 and D2 through the lower and side openings, keeping the assembly loose.
Insert D3 and D4 from opposite sides to build the outer lattice.
Slide C1 through the central channel at stages 13–14.
Insert D5 through the last open channel and rotate the completed assembly to lock it.
