Wits End / Eureka Puzzle
This is a Puzzle invented by Robert R. Boomhower in 1966. The patent for this puzzle is expired. I saw a "Wits End Puzzle" on youtube and it looked like it would be fun to make. I designed (reverse engineered) this puzzle to be super easy to 3d print. The point is to remove the ring from the puzzle. You will need a 24" inch string or wire. I used wire with zip ties on the end.
