About this 3D model

I designed this puzzle after the classic wooden version. The idea is to free the ring around the base. There are two versions, the first level, which is without the looparound the base, then the second level, which is with the loop. You will need about a 10 inch long piece of paracord, or other string, at least something that you can tie a knot at the end and it won't come out the holes. Enjoy:)
