Oh, that's cool. I built one myself with LDD a few months ago. I think, we both did it the same way. I have LDD instructions and a picture with a disassembled corner piece on my page: http://www.mocpages.com/moc.php/287614 Check it if you like.
Amazing! It looks like a lot of work went into this. Especially the case! Great design..I've really got to try making one of these someday...It's always astounded me how the pieces fit together so perfectly.
