The Bowen knot isn't actually a knot - topologically, it's an unknot. However, it's widely used in heraldry and has become familiar on the Apple command key, ⌘. https://en.wikipedia.org/wiki/Bowen_knot The OpenSCAD script was created using this design tool. Unfortunately, it doesn't work properly in the Customiser. You can adjust the value of Base to create a flat base suitable for FDM printing or remove it altogether for SLA printing. http://kitwallace.co.uk/3d/functional-objects.xq?design-id=fd86c99b-e5d8-4d73-89ee-56114bb12440
