Rotate the creme filling for satisfying clicks!
As you rotate the filling, the spring arm will move from one position to the next, giving you a nice tactile feel. This model was designed to be the actual size of a Double Stuf Oreo (with extra creme for a better grip).
Assembly
Start with one wafer piece upside-down. Glue the center gear into the center of the wafer. Stack the creme filling onto the wafer, ensuring that the tip of the spring is inside the gear. Glue the second wafer onto the remaining end of the center gear.
