Description
This is Karill's Devil's Knot puzzle, but then scaled down to 2/3 size (60mm lengths) with tolerances modified accordingly.
There are multiple variations on this puzzle, and all the solution videos or images I could find were for other variations only. And no, the numbering of the pieces is not the order in which they need to be assembled.
