Parts List:

• Plate 2 x 3 (3)
• Technic Axle Pin (1)
• Technic Brick 1 x 6 (1)

Notes:

• Notice that the small chunk is now 2 layers higher than the main chunk.
• Piece clarification:
•     Technic Axle Pin: This is a mix between a pin and an axle, allowing you to, in this case, connect a free-spinning gear to a Technic brick.
