5th try, period 5. Whoo! It feels good to be back. I hope this does well. I figured out the 6i end sauce, found it worked on period 3, then struggled with the geometry of the rest of it for far too long. As it is I don't see a way to cut a debonder. Maybe arm 2 can be cut, and arm 3 increased to 4i to make up for that rotation.
