RingConn Gen 2 Ring Sizer (Fixed Size 9 Fit)

A corrected ring sizer for the RingConn Gen 2 smart ring, specifically addressing the tight fit issue on size 9 fingers.

The original sizing guide can run slightly small, and this print provides a more accurate physical reference to confirm the right size before wearing the ring full time. Simply test fit on your finger and compare to the included size markings.

Print in PLA at 0.12-0.16 mm layers for smooth surface and accurate bore diameter. Avoid scaling unless you are explicitly testing tolerance variation.
