Can I Use a 3D Printer to Print the Sizing Kit?

If you have access to a 3D Printer, you have the option to print Oura's sizing kit rings.

Things to Keep in Mind

  • The file format is .stl
  • Each ring is its own file
  • Begin by printing 2 – 3 ring sizers. If these don't fit, print a few more.
  • Choose high-quality material for printing. If you use a coarse material, the results may not be optimal.

When you've chosen your size, feel free to pass the rings along to a friend or family member who may be interested in Oura. Otherwise, please recycle them according to your local recycling guidelines.
