Combination Lock

This lock contains four wheels, each with the numbers one through eight. The wheels are named for the number they add to the lock's code. For example, if you wanted to make a lock with the code 1-2-3-4, you should print wheels 1-4.

THE CODE IS NOT ADJUSTABLE ONCE YOU SNAP THE LOCK TOGETHER.

How to put it together:
First, push the wheels into the holes in the side of the main body (you may have to push hard, but they will go in). Next, you insert the internal bar into the middle of all the wheels from the top. Because the lock bar is designed to not come out of the top cover piece, you must slide the cover around the U-shaped part of the lock bar before snapping it into the four holes at the very top of the main body.
