Inspired by the White Marble Knot 9" Sculpture from Crate and Barrel, I designed this interlocking knot.

I decided to print it as 4 half rings and combine them using octagonal pegs. The reason behind octagonal peg design is ease of printed and also give the ability to change the shape of the final model into any variation you'd like.

In this model I am including a combined file, as well as half rings without pegs in case you wanted to design your own. I am including pegs with an offset ranging from 0.1-0.3mm
