I did not create this but I found it as a good ball machine element. A K'Nex education set had instructions for this and called it the "Archemedes Screw".  If you put a ball at the top of the chute, and add a motor, the ball will go down the chute slowly.  Just saying... this element moves slooow. You can use it when you wnat to add time to your ball machine.  You can also use this as a lift if you have a strong motor. Sorry this element may be a little unsturdy.  It's a fun build though so give it a try.

It's *want <br>
