A modular ring project. Simply print out a ring the size you want it, print out a topper, and put them together.This set features a pattern of dots on the inside of each ring to help you remember what size the ring was (since it can be hard to tell them apart by eye). Or print out a whole set to help size them for friends and family, and then know which one you want to print out (to avoid problems with shrinkage or mis-calibrated machines). The one shown is size 12.The negatives are also included to help you make your own toppers.
