Introduction: Big Wheel Ferris Wheel | a K'nex Ball Machine Element

About: 3D printing enthusiast

Hello! Here is an element from my K'nex ball machine Freestyle! It was featured in path 3 where it brought the ball to the white floor at the bottom. I created it because I really wanted to find a use for them wheels! A disadvantage to this was that they were really heavy, so the challenge in building this was to support the rods. This is quite a small 'ible, and a very easy build. Want to build it? Well lets go!
