Expandable Mechanical Nozzle Box

Once I had the idea for this, I had to see if I could get it to work. It's not perfect but It's pretty cool if you ask me.

mainGear and Exterior have to be printed at the same time and centered relative to each other. Each section can hold three nozGears. Once everything is printed, gently push the nozGear pieces into the slots at the same time. I don't have a way to keep them from coming out but I've found that its not something you have to worry about if you don't push the nozGear out too far past the second full gear. It can take a few moments of trial and error to have all the layers aligned but it has never been much of a hassle for me.
