I present the cosmological model which approximates the periodically distributed dust overdensities on the Einstein-de Sitter background.
The model construction enables application of the Green-Wald averaging scheme and the Buchert averaging technique simultaneously.
The comparison of the angular diameter distance obtained within the presented model and the angular diameter distances for the respective
average space-times is given.
