Do you have access to a 3D printer? Do you want to print your own ring sizers for the new Oura ring? Here's how to get started.

  • The file format is: .stl
  • Each ring is its own file. We recommend that you start by printing 2 – 3 ring sizers and trying them on first. If they don't fit, print more sizers.
  • Choose a high-quality material for the 3D print. The inner surface of the new Oura ring is very smooth, so if you do the ring sizing with a coarse 3D print, the results may not be optimal.

When you're done with the 3D printed rings and you don't need them anymore, you can pass them along to a friend or a loved one.
