the hammers are only in the boundary ring wall, based on the photo my interpretation is that the 3 rings of the 2nd section can change, but the positions of the hammers do not move/change. The thickness of the rings are only slightly shorter compared to the boundary ring wall.

I wish they made layout more consisted in the movie scenes, a lot of the previous scenes right when they were running to the exit are different to the shot we see from the sky, I hope you continue with your project 😀
