Stop guessing with paper charts or measuring tape! This US Ring Sizer Kit allows you to physically wear the sizes to ensure the perfect fit for your next jewelry purchase or 3D printing project.

Unlike paper strips, these rigid 3D printed rings accurately mimic the feel of a metal band, helping you test not just the finger diameter, but whether the ring can comfortably pass over your knuckle.

📏 Sizes Included: US Standard Sizes: 5, 6, 7, 8, 9, 10, 11, 12 (No half sizes).

💡 Nozzle Recommendation: For the sharpest details (especially the size numbers on the rings), I highly recommend using a 0.2mm nozzle. However, a standard 0.4mm nozzle prints these okay and they will still work perfectly.
