NEEDS TO BE MOVED ONE AND A HALF TICK INTO PREVIOUS BUILD Unfortunately I couldn't find a way in my head to make quick snapping possible.

Fits on a foundation. Walls and ceiling placeable without clipping. One more half tick to the left/right, super tight to ceiling. Moved closer together. Not cleaned for reference.
