To kind of clarify the physics that creates this phenomena, filament shrinks as it cools. So if you have let’s say a floor butting up against a wall, that floor has more filament in the X and Y axis than the upper layers of the wall which have nothing but air. So as the filament shrinks, the floor is going to tug much greater than the space on the wall that only has air behind it.
The setting can be found in the quality tab. You can do it either as a global setting for all objects or click on the objects submenu and navigate to the quality tab and apply the setting to a sole object. By forcing the model to be built from the outside in, change the order of how the wall is constructed. What this will do is allow for the outer wall too cool before the inner floor is laid down. So as the floor shrinks, the wall is “stiffer” as a result of having had time to cool.
One other trick you can do to mitigate this phenomena is to thicken the walls of that model. Again, it can be done globally or on a per object basis. By thickening the walls, even when the floor does shrink, there is more wall material to combat the tug of the shrinking floor.
