It's KneXFAN200 here with a k'nex ball machine contest. There will be no prize unless you count being put on a collection of best ball machines with instructions. There will be a Grand winner, a First place winner, second pace winner, a third place winner, and a runner up. So lets get to the rules. First of all, it needs to be a ball machine that is new and has instructions. I'll make an exception though, you could do a ball machine with instructions that was made from May, 2016, and up. What you will do is make the ball machine first of all (unless it's built from May 2016 and up) and post it on instructables. Then, you put the ball machine link in the comments or just by emailing me on instructables. After that, I will put a picture of it on here and once there's enough ball machines or by the start of March, 2017, the winners will be announced and will be put in the collection (in order) that I talked about at the beginning. One more thing, I am not entering this contest.

Thanks and good luck,


OKAY! THIS CONTEST HAS ENDED! Grand Prize Winner... The Knex Inventor! First Place Winner... random_builder. Congratulations everyone! New K'nex ball machine contest coming in at least a week!

Yay, I win. Will you subscribe to us? Where is the collection with these builds in them?

I did subscribe to you and sadly, I can't put it into a collection and post it until there is 5 or more instructables in that collection. So once the winners of the other ball machine and gun contest wins, i'll put them into the collection and finaly post it.

Does this one count? It was working, but I lacked the pieces necessary to finish construction.

I'll count this just because I want you in it. Thx!!! Also, could I use this for a knex ball machine? I'll give you credit! nd yes I can see how to make it from the pictures.

Oh. Sure, you can use some of the mechanisms in another ball machine. As long as you give credit to me.

If I can even start building it. I am busy right now. If I can sometime bouild it, then yes, I will send you a link.

I might try to make a bigger knex ball machine. My small definitely won't win. I never made a very big ball machine, so I might give it a try.

Ok! I could enter your ball machine (if you make one) if you send me a link. I won't replace the other one. GOOD LUCK! If you need any help,just tell me.

And also, this isn't all juged by size, just a little bit. It's also juged on paths, structure, and theme. Again, GOOD LUCK!

Well, I thought about it more and I don't think I will make a bigger one. I don't have a youtube account and I don't want to make one. I don't have very many knex and I don't have a knex ball. I probably won't be making a bigger one after all.
