A model created 'Just For Fun', which can used as a ring for partners.Different ring sizes for ring fingers of ladies and gentlemen are possible, whereby the original design is maintained. Outer- and inner diameter has to be changed, so that the thickness of the ring always remains the same.The ring size of my model is "59", that means, that the inner diameter of the ring is defined by ( 59 / Pi ).In this case the diameter is rounded up to 18.8 mm.The outer diameter of the ring is 21 mm.The ring width is 6 mm. The ring thickness is 1.1 mm.The model is available as a STEP file (.stp) only.
