Introduction: Knex Ball Machine Element: Gravity Star

Picture of Knex Ball Machine Element: Gravity Star

Hey everyone,

Here are instructions for one of my best elements so far. It works with gravity, a locking mechanism and uses 8 knex balls. You just need 1 special piece that I like to notice (see step 1). It works 95% of the time and is easy to build. If you want to see it in action you can always watch the video.

If there are any problems/ questions feel free to ask me in the comments below.

Thanks for watching/ building,

Thibault Art.

Now you need to put 7 Knex balls like this. And drop the 8th ball on top like this.

WOW!! Awesome build! I was 2 hours late for work because I just had to finish this element to see it work... This element holds most of my collection of balls... guess I have to go find more.. I have to use this one in one of my machines...

I'm really happy to see that this element inspired you that much! hopefully they weren't too angry at you for being late XD. I'm looking forward to see it in your next build. :)

This one I made too, I already had an element like this but this one is much better and more piece consuming: exactly as I want, thanks for instructions
