to whom it may concern: the cut out is Right after the book 346x211mm. you guys in America have to divide it by 2.54 
Well, id did that exactly after the book and found out, that there is About 2mm space on each side when you follow These values. From my Point of view thats a Little bit too much, there is nearly no space left when you make a Little mistake when measuring/cutting.
I think it is better to reduce the cut out Dimension at least one Millimeter, will do the trick better
