Ornaments Based on a Stone Carving

Here are some ornaments based on a Celtic stone carving in Meigle, Perkshire dating back to the early days of Christianity. They could serve as key chain markers or be made into a decorative brooch with the addition of a jeweler's pin back. Run in default mode the OpenSCAD code creates a Celtic Knot Ornament like that on the stones. A second ornament was made using a different set of knots. It does not have the Celtic pattern.
