About this 3D model

I make this dummy Oura rings for testing which size is the best for your finger. I make it with the table at Reddit: Size: Finger diameter / Diameter with sensor 6: 16.76mm / 15.21mm 7: 17.60mm / 15.97mm 8: 18.43mm / 16.81mm 9: 19.25mm / 17.63mm 10: 20.02mm / 18.41mm 11: 20.81mm / 19.24mm 12: 21.64mm / 20.05mm Tested at size 8. Printed with PLA. My step files are created with FreeCAD Oura Ring Gen 4 set here: https://makerworld.com/en/models/1359969 Oura Ring Gen 5 set here: https://makerworld.com/en/models/2881988
