This model is sometimes also called "magic rings" or "impossible rectangle". You could also call it "Borromean Rings": three rings linked in a way that by removing any one ring the other two aren't linked anymore, either.
I'm not sure about the model name, but it's at least a similar model. I think "Before the Big Bang" is a design by Thoki Yenn, but again, I'm not sure. All pointers would be appreciated.
