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.

To download the Oura Ring 3D Printing files, please click here.

Once you have determined your Oura Ring size, you can select it directly from the dropdown menu on our purchase site.

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

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.
