 We now need to assemble a chute.  Cut a 4"x10" piece of cardboard.  Then cut the cardboard down the middle length-wise, but only cut through the first ply of cardboard.

 Fold the cardboard into a right-angle and glue a right triangle with 2" legs to the end.  Let this dry.

 The funnel/valve assembly fits into a "track" in the box.  Slide the funnel/valve assembly in the box and mark where you want to place the track.

 Cut out some strips of cardboard and glue them to the inside of the box to make the track for the valve assembly.

 Next, cut a triangle to fit the chute in the funnel/valve assembly.

 Putting everything together is relatively easy.  Slide the funnel/valve assembly into the box with the chute inserted and then push the chute through the triangle hole in the box before completely sliding the funnel/valve assembly into the box.

 You can use some wire nuts to attach an extension cord to the solenoid, or just twist the wires together and use some tape to keep them from shorting together.  The polarity doesn't matter.
