The file 'Full Size Hula Hoop!!! 3D Printer Model' is (stl) file type, size is 146.8KB.
This is sort of a joke.. i have no time to make this, nor do i have the skill to try it out, but ALL my maths should be correct! More power to anyone willing to make it ... print the hula hoop.stl file 16 times and some gluing.
