Here's a hastily shot video that show how the series of 5-piece rings come together to form the icosahedron: http://www.youtube.com/watch?v...

I used PLA, 2 shells, 75% infill, standard (0.20mm) resolution, no raft. Print time was ~ 2 hours for the entire design. Use clear PLA for a realistic looking snowflake.
For assembly, connect the notches in the snowflake together, using the picture as a guide. Make sure the notches slide all the way together. (Hint: start with 5 snowflakes connected in a ring, as shown in the picture with the green snowflakes. Think of it as a soccer ball with only the white hexagonal faces).
If the fit is too tight for the material you are using, scale the model up 105%.
For a smaller ornament, you can construct an octahedron, using only 8 snowflakes instead of 20.
