We went to a big box lumber place (Lowe's maybe?) And bought this piece. It is designed to fit on the top of a rolling Husky tool box. It slides over the sink easily. We left ours snug where it goes over the faucet, this keeps it from "drifting" while we travel. It stayed snug when a drawer didn't. We trimmed the length a little, used a hole saw in the drill, and made two cuts. Simple, works well, adds usable counter space, and hides dirty dishes.
