How to draw a precise celtic knot

How would one go about creating this Celtic knot in Illustrator without tracing over the edges?

It seems to be like a Möbius strip making it rather complicated to draw with mathematic precision, I have tried using triangles and circles in various ways but nothing seems to work.

Answer

  1. Draw a triangle and flip it vertically.
  2. Draw a circle, with the origin on one of the triangle vertices
  3. Copy and paste the circle, and move to intersect the circle centre with the remaining triangle vertices.
  4. Remove the triangle.
  5. Select all, and apply a wide stroke to the circles
  6. Click Object > Expand
  7. With the Shape Builder tool, delete the parts of the circle you don’t need.
  8. With the Shape Builder tool, join the shapes to make the illusion of the overlapping parts.
  9. Apply a fill and stroke as required.

Alternatively rather than circles you can also use ellipses, with each ellipse rotated 120 degrees, which is slightly closer to the shape of your original.

You could also use this same Shape Builder tool technique for drawing more irregular shapes, and rotating each part 120 degrees around a triangle. This is even closer to your example, but less regular.
