This my very first Instructable. It is my ball machine element called The Catch Basket Zigzag. When a ball enters at the top, it zigzags through the different catch baskets and goes out the exit track. You can make it is tall as you want following the pattern I have created. Just make sure the ball zigzags and doesn't slide down the catch baskets. Below is the parts list for an element with 3 catch baskets.
