Starting with three overlapping circles (see https://www.talkgraphics.com/showthr...a-Venn-Diagram), can you construct a set of Boromean Rings?
The key feature is if you remove any one ring to find the other two are not linked.
The follow-up question is how make cuts and re-welds would you need to join three solid rings into a Boromean Ring?
