IQ Test Puzzle

Goal of the puzzle is to remove the ring without breaking anything.

IQ Test puzzle modeled from the one sold by PuzzleMaster. It does have a slight change to resist the brute force way to solve it. Requires a piece of string that does not stretch.

The tolerances are very tight for the puzzle to work and designed for a .4mm nozzle and to be printed with at least a 4mm brim to so the ball does not move when printing.

When knotting and tightening the string the pieces should all be in place like picture three, where the ring is just below the word IQ. The string should be as tight as possible so that the ring cannot slip under the bottom and be pulled off without solving the puzzle. The ring should be stopped by the notch on the left side with the string fully stretched.

Good Luck and enjoy!
