Truncated Octahedron Construction Kit

Pieces to construct a truncated octahedron. For a single truncated octahedron, you will require:

48 corner pieces
36 edge joiner pieces

Assembly via squares (for one truncated octahedron):

1. Pair up corner pieces and join them together at right angles by slotting the corners into each other to make a star-like shape.
1. Create a square shape with four corner stars and four edge joiner pieces. The corner stars should be oriented to create a horizontal plane, with the edge joiners placed vertically between them.
1. Repeat the previous step five more times to create six square shapes.
1. Attach four joiners to one side of a square shape to make a square boat-like shape with four upward-facing prongs.
1. Repeat the previous step, leaving two boat-like shapes and four free squares.
1. [fiddly] Attach four squares vertically in a diagonal / diamond configuration to one of the boats; stabilise the diamonds horizontally with four additional joiner pieces.
1. Turn the other boa
