The file 'Ball In Ball FIXED And Flat To Horizontal 3D Printer Model' is (stl) file type, size is 5.4MB.
The file is identical to the source I remixed from. I just oriented it (by eye, sorry) so one of the hexagon faces is flat to the print bed. It printed fine on my toybox (at 0.7 scale) without any supports. The ball removed fine.
