Benchmark tests for "no-fit polygon"

I'm currently researching on packingproblems, and found a lot of articles about this kind of problem. Many of them try to solve this with the help of the "No-Fit Polygon" and test there algorithms against some datasets (Albano, Blasz, Dagli, Dighe, Fu, Jakobs, ...). But I was not able to find these benchmark datasets on the web.

Does anyone know, if there is such a website or a repository, and if yes, a link to this page would be nice.
