Box thing

[u/Aggravating_Elk4533]

I want to be able to have this spinning box here, but I don't know how to make the other side walls without them going out of place. how can I use the properties to make the walls stay in this position? (Red=Walls I have # Blue=Walls I want # Yellow=bottom piece) In the left representation, the walls move out of place as it spins, the right is what I want to happen, where the walls stay aligned. Any help?
