This is an impossible object: the puzzle is to decipher how it was made!
The Monkeys Nuts is Two Brass Monkeys take on Scott Eliott's "Its Nuts" design. Originally only available in 3D print by Scott, our version is a beautifully crafted solid brass bolt with two nuts threaded on it. But all is not as it seems! A fine piece of mechanical engineering makes this bolt very, very special.
To remove one nut turn it clockwise. To remove the other, turn it counterclockwise. If you hold the two nuts and rotate the bolt they each move in different directions...this is seemingly impossible, as the bolt has the same thread along its length.
Milled from solid stock and measuring nearly 3" x 1", the entire assembly weighs a whopping 1lb. This thing is large, and VERY well made.
It’s not a puzzle, it’s more like a brain teaser or an impossible object. It's a substantial, elegant item to hold and play with, carefully machined with a simple but clever trick. Playing with it makes me grin.
