This step builds the conveyer pusher and the calibration stick, which are loose parts that are not attached to the sorter machine.

The conveyor pusher will be placed behind the pegs on the conveyor, as shown below.

The calibration stick is used to calibrate the light sensor.  See "Using the Peg Sorter" below.
