When I printed the original, I couldn't get the letters at the top of the tower to print correctly (at least at the model scale I was using). I decided to modify the balcony ring that reads "Planet Express" with slightly thicker walls.

Depending on your print settings, scale, etc you can force the lettering-background only, to print solid. Other settings will force the entire-balcony ring to print solid. Check your slicer preview to make sure it will print the way you expect.

Since the original design builds the balcony and lettering starting at the top of the base of the tower-top, I was able to use side-angle snippers and a razor blade to easily and cleanly remove the original/failed balcony portion. Then, this remix fit right on top. I glued it from the inside of the balcony ring, so it didn't show through. Sure it's not 1 piece now, but it's a natural break in the model and no one will know better
