We used 3 of the grids to make the top/back part and used zip ties + the connectors to keep that secure and immovable. Then we went to Home Depot and bought a wire shelf that had a bit of a lip on it to be the front half of the top, and able to flip up when we need access. We secured that with zip ties again. It works for us! Experiment and use lots of imagination and you'll be successful!
