Even better:
If any part of the box will be cut, don't generate that box. Then, go 
through again, and make a union of the boxes that will be cut (minus the 
ones that will be removed completely)...difference from that.

Alternatively, loop through once, if the block is partially cut use a 
difference *for that block*. This uses many differences of single 
objects instead of one difference of many objects, only requires one 
loop and simpler code, and is probably faster.
