Protagonism - KNEX Ball Machine




About: I like to build with K’NEX as you can find many things I’ve built here. I also love to watch YouTube videos, have played piano and drums for over 10 years, listen to music (not country), and play video games...
My most complex and best k'nex ball machine to date is finally here! This ball machine features 2 networks (2 lifts), 7 paths, and 10 new elements. Be sure to check out my guide to elements to see my new elements at detail.


Step 1: Network 1

This network has 3 paths with Thibaultisthebest's Simple Modified Stepper Lift I modified.

Step 2: Path 1

This path features MinnesotaRandomCrap's double dropper and the crankshaft for network 1's lift that pushes back depending on when the balls will get to that point.

Step 3: Path 2

This path features 4 new elements: Mario's Randomized Dropper, Mario Kart Paving, Basket (new type), Super stairs. Also features Kairah89's separator (doesn't work so well for me).

Step 4: Path 3

This path features 2 new elements: Alternating Stairs and Lid Fall-Through.

Step 5: Network 2

This network has an ordinary chain lift and 4 paths.

Step 6: Path 4

This path features sandroknexmaster's Horizontal Clickers and the Single-Rail Fall-Through.

Step 7: Path 5

This path features 2 new elements: Blue path (my version) and Tippping Fall-Through. Also includes includes Regular Fall-Through.

Step 8: Path 6

This path features one of Knextreme's stair types, Large Alternator, Super Path, and Knextreme's Bendy Paving.

Step 9: Path 7

This path features 2 new elements: Elastic Panel Maze and Downward Coaster Pathing. Also includes Red (Metallic Green) Rod Fall-Through.

    I got the black/white balls from the Motorized Madness Ball Machine set. The yellow balls have the exact same diameter as those and are wider than the original ones. That makes it hard to make elements work for them. I happen to be one of those rare people who modifies elements to make them work with the newer balls.

    I think it would be a good idea if you used light grey connectors on the chain lift instead of red. it looks better. I love the network 1 lift! keep up the good work!

    Thanks! I do try to think of ways to make ball machines as big as I can and try put as many interesting elements on as I can.
