I saw this bar game that was made out of wood, so I wanted to design it in 3D as a printed project. All you need is to measure the string from the top rings to the bigger ring that is on the hook in the middle and tie it to each. A shot glass is placed in the middle space and each successful swing and hook moves the glass forward to the next space. Once the glass is moved completely to the other player's side they must take the shot. My kids love playing with Dr. Pepper! Enjoy.
