assembly

• See layout.stl for overall placement
• Print domino_machine_arm_block.stl and domino_machine_rail.stl, and glue
• Print domino_machine_arm.stl and attach to SG90
• Print domino_machine_servo_bracket.stl to fix SG90 (2x20 tapping screw)
• Print two domino_machine_wheel.stl, attach the O-ring, and attach to the SG90-HV
• Print domino_machine_cart.stl and install SG90-HV and wheels
  Attach the cart to the rail (loosely attach the 3x8 screw)
• Place Arduino on Cart (fix it with GEL ELASTOMER etc.)
• Print two "compact AA battery box 2"(Remix Source) and Place on the cart
