STL: the metal only, ready for a slicer or a casting house. 3DM opens in Rhino and Matrix with metal and stones on their own layers. OBJ and GLB include the stones. All in real size.

The model

What you're downloading

  • Hoop: 25 mm across the outside, a solid 2.5 mm round tube.
  • Ear wire: 0.8 mm (20 gauge). It tapers out of one end, crosses the gap and slips 3 mm into a hole in the other end, with 0.1 mm to spare.
  • A pair: the file is one earring. Print or cast it twice.
  • Files: built in your browser when you click, exactly as you set it. STL, 3DM and OBJ are in millimetres (STL and 3DM Z-up); GLB is in metres, as the format requires.
