This solution, despite my general enjoyment of the aesthetic, is aggravating for several reasons. 

First and most important is the fact that due to geometric constraints, it's outright IMPOSSIBLE to assemble the center product without moving a conduit or moving the product itself. The reason for this is there's no combination of bonder and arm position that allows for full access, which is necessary to use a bonder with only single atom inputs. 

The other aggravating factor is that I'm certain that I could do better with this layout. I know there's cycles to shave somewhere, but I'm out of time to do it.
