The centroids are not updated automatically for performance reasons. You can easily update it using the update_centroids method though: https://github.com/wolph/numpy-stl/blob/26c9332427de1d49aefb6831b1073e3d3ed71ce3/stl/base.py#L348-L349

Or call the update_normals method which updates the centroids as well by default
