About this 3D model

This is a cryptex game designed to help students learning basic addition, subtraction, multiplication and division. Once they find the solution to the equation the cryptex will open and reveal whatever prize is left inside! The equation tumblers on the body do not effect the locking mechanism. They can be turned and snap into place to create numerous equations. The 2 tumblers on the cap are what lock and unlock the cryptex. They are designed to be able to change the answer to unlock it to match the answer to the equation on the body. Check the instructions for more info on assembly and how to change the unlock code. Enjoy!
