Computer's Choice 10 burr puzzle

For those who just can't get enough of burr puzzles...
This puzzle's design pulled from the now defunct IBM research page. It was categorized under General higher level burr puzzles. This is a level 10 puzzle with a unique solution. These pages are still available through internet archives, see the links at the end of the wikipedia page.

Note: I rotated piece 4 to turn an overhang into a bridge. This built cleanly on my cupcake with minimal sagging at the default size 6.
While I found the Philippe Dubois burr slightly challenging, I found this one much harder.
I have uploaded the puzzle file for Burrtools, see Burr Tools on sourceforge which can animate assembly too.
