Ribbed Ring Pendant Charm

A weighty little ring with a stack of grooves and a loop ready for a chain. This charm is a short, thick-walled tube, a ring you wear as a pendant rather than on a finger. One face is smooth and clean; the other steps down through a series of concentric ridges, like the threaded neck of a bottle or the fins of a camera lens, so light rakes across it in bright bands. A small rounded bail sits at the top, drilled through and ready to take a jump ring, cord or chain. The open bore means you can thread something through it too, a rolled note, a second cord, or a keyring split-ring. It works as a minimalist, industrial-style pendant, a keychain fob, a bag charm or a chunky zipper pull. Print notes: • Prints tidily in resin for the sharpest grooves; on FDM use 0.12 mm layers so the ridges stay distinct. • Stand it on the flat ring face with the bail uppermost, minimal supports, and the concentric detail faces outward. • Scales cleanly: shrink it toward an earring, or grow it into a napkin ring or scarf ring. • In castable resin it takes lost-wax casting well; brass or bronze suits the mechanical, hardware-inspired look.
