When you look for other projects on the internet, it´s of use to know that every language has its own name or definition for it.
In German it is called "Krippe".
In English it´s called "nativity scene" or "nativity set".
And it usually goes with the definition of "clay" or "polymer clay".
In Spanish you´ll search for "belén" or "pesebre".
But where I got lost were the incredible hits I found in portugese speaking countries.
I am still amazed by project of people in South America, like Brasil.
They call it "presépio".
And what´s very common there is homemade "porcelana fría" / "cold porcelain".
I also looked for videos of other fans on the internet!
