Here it is fans! The Wrath of Khan Communicator.
This is the bulky often said HOKEY communicator which Kirk uses to talk to Spock.
I have put this together and it is very good, although without color ink it makes it look somewhat terrible, also I noted small tweaks that I had to make in order to make it work, so I incorporated these into the model. Use toothpics or maybe a couple of paper brads to make the grid flip open.
