-wait for piper to walk past the entrance.
-Go right and once piper has turned the corner go into the room at the end of the hallway on the right
-wait for striker to pass, I waited behind the little desk so he couldn't see me through the window
-Follow the hallway straight to the ink glob, being cautious as you are following pipers path
-Once you have grabbed the ink glob, go as fast as you can on the way back you came.
-Grab whatever pipe piece you need from the pipe making machine, you can also ignore the ink demon
-Place the pipe in the missing pipe spot
And that's it! you rinse and repeat till you have all pipe pieces! Its best that you try and do this as fast as possible, as to keep in time with the Butcher crews cycles.
Feel free to message me if your having trouble getting the achievement.
