3D Ring Sizer Set: Discover Your Ring Size with Precision and Ease

I have created a set of 3D ring sizers, a simple and completely free collection of tools that will help you determine your ring size accurately and easily. Each ring in the set has the EU size engraved on one side and the inner diameter on the other, allowing you to find your exact size without complications.

To ensure the accuracy of these rings, I have also developed a calibration negative for some sizes.

Before Printing:
To ensure that the rings represent the sizes accurately, it is useful to calibrate the XY Size Compensation parameter (in PrusaSlicer, check what it's called in your slicer).
This calibration is done by printing a negative and a ring of the same size (choose the closest to the ring size you think is appropriate, if you don’t know, choose EU 60 which is the middle size).
Try to fit the ring into the negative. If it doesn’t fit, enter negative numbers in the XY Size Compensation (e.g., -0.05mm, keep testing). If it fits too loosely, enter positive numbers in this parameter. The goal is to require some force to push it through; even if it gets stuck inside, that’s okay, but it should pass without gaps.
Once this parameter is well compensated, print the rings you think necessary and keep testing until you find your size.

My 3D ring sizer set is a practical and accessible solution for everyone who needs to know their ring sizes, whether for making an online purchase or just to know their current sizes. Easy to use and accurate, I designed this set with the aim of offering a simple and effective way to measure your ring sizes, completely free of charge.
