We give an alternative construction of the Kontsevich-Kuperberg-Thurston invariant for rational homology 3-spheres. This construction is a generalization of the original construction of the Kontsevich-Kuperberg-Thurston invariant. As an application, we give a Morse homotopy theoretic description of the Kontsevich-Kuperberg-Thurston invariant (close to a description by Watanabe).
