The file 'Star Christmas Tree Topper 3D Printer Model' is (stl) file type, size is 13.4KB.
I couldn't find a basic star with clean flat faces so I modeled one for myself. I recommend printing it upright with zero bottom layers (to make the hole) and supports for the bottom edges of the spokes on the star. I attached an image of the supports I had, it makes a thin wall. It took about 1.5 hours to print at 0.24mm layer height.
