About: I like to build with K'nex and Lego.

Here are the instructions for the elements I used on my ball machine Grid Tower II.

Have fun!

Step 1: Three-Ball Release Mechanism

I used this element on Path 1 in Grid Tower II.

Step 2: Wheel Slope

I used this element on Path 1 in Grid Tower II.

Step 3: Soft Landing Freefall

The Soft Landing Freefall uses rubber bands to help balls land more softly, hence the name. I used it on Path 2 in Grid Tower II.

Step 4: Blue-Green Ball Arm Stairs

I used this element on Path 2 in Grid Tower II and on Path 7 in Rujebime.

Step 5: Green Connector Tunnel

I used this element on Path 2 in Grid Tower II.

Step 6: Trapdoor Track

I used this element on Path 4 in Grid Tower II. An interesting thing about this element is that if the ball enters with enough speed, the trapdoor will not trigger.

Step 7: Boat Arm

I used this element on Path 4 in Grid Tower II.

Step 8: Simple Green Ball Arm

I used this element on Path 5 in Grid Tower II.

Step 9: Clockwork Arm

I used this element on Path 5 in Grid Tower II.

Step 10: Square Pannel Stairs

This is probably the simplest element in this Instructable. I used it on Path 6 in Grid Tower II.

Step 11: Light Gray Connector Pathing

This pathing is quite useful if you have a lot of light gray connectors that you want to use up. I used it on Path 7 in Grid Tower II.

Step 12: Zigzag Tubing Connector Pathing

I used this pathing on Path 7 in Grid Tower II.

Step 13: Chopstick Pathing

I used this pathing on Path 7B in Grid Tower II. Chopstick Pathing also makes a great fidget : ).

Step 14: Ball Painter

I used this element on Path 7B in Grid Tower II. This element looks best when it is covered with paper or panels so you cannot see the inside.

Step 15: Drawbridge

This element is my biggest and most complicated element, so be sure to follow the instructions carefully. I also like to call it my masterpiece. I used it on Paths 8A, 8B, and 8C in Grid Tower II.
