3-Sided Figure 8 Knot Pendant

This was the first Figure 8 Knot Pendant design I made, not Mobius type, that is, with 3 sides and 3 edges. The triangular cross section is actually a hypocycloid curve (concave triangle) but with the sharpness at the vertices rounded to meet the printing requirements (no thin walls). It is hard to see the difference between this model and the (1-Sided) Mobius Figure 8 Knot Pendant, but there is a very significant topological difference.
