I have been modeling and printing the Emperor's Throne Room from Return of the Jedi. I cut the window ring in quarters so you will need to print 4 of those.
...Plus You will also need 6 of the outer ring pieces. I made these to accompany the 'Final Duel' set I bought in the late 90s.
Update:
I just sliced the squared ring into three pieces. I was rather large to print. Now it is more manageable. There are mirror halves so you will have to print two of each part.
