This is a great element. The instructions were nice and clear.

I had a problem with some balls getting stuck in the entrance. If I threw them down, they went through OK but if I dropped them, sometime they got stuck.

I've had this problem with other elements I've built. I'm not sure if the balls I use are slightly larger than normal. I do have a mixture of brand new and old used balls so I don't know what's the problem.

However, I made a change to the entrance to make the opening a little larger and now it works perfectly. I've included some images to show what I did.

Thank you for building one of my elements.

the modified entrance you made looks really well done.

It's true that the new knex balls are slightly larger than the classic knex balls.The new knex balls are also much lighter than the classic ones which also might cause some malfunctions in some elements.

But I'm happy it turned out well,

thanks for building!

I just added this element to my new ball machine, "möbius"! I already added your other elements to my ball machine too!

Thanks. I can't wait when Möbius will be ready!
