Borromean rings are three simple closed curves in three-dimensional space that are topologically linked and cannot be separated from each other, but that break apart into two unknotted and unlinked loops when any one of the three is cut or removed. [1]
This is an Algebraic link diagram version. The model can be printed in-place (with supports), or as three separate pieces (and forced into position).

The author marked this model as their own original creation.
