Disentanglement Puzzle

thingiverse

I saw this puzzle posted on reddit: https://www.reddit.com/r/mechanicalpuzzles/comments/js0ajc/i_had_this_on_my_desk_up_until_the_pandemic_began/ The goal is to disentangle the rope from the puzzle. I designed this puzzle to be printable without support. The steepest overhang is 45 degrees, and the rest can be done with bridging. You will need a little bit longer than one perimeter of the puzzle of rope or string. The holes on the bead are designed for a rope that is about 0.5 cm in diameter, but to be honest, I don't actually sure if the bead is actually necessary. I designed the inside of the bead to open up a little to hide the knot in my rope. Just print, tie the rope on as shown in the picture and enjoy.
