I made it from a instructable from this site but it didn't work well, So I modified it and here is the result. It has 2 paths. 1 where the ball goes up the lift and back down fast and off the machine. When you flick a part over , it changes route , going onto the balcony at the top of the lift and down onto a previously moving part, which is now fixed in place. After this it then goes through a path and into the ball holding area. This is the routes of my ball machine. As it is my first ever knex ball machine, it is not going to be massive but it is a good attempt for me. Please vote and follow me. If you have a 3DS or 3DS XL i'm happy to trade friend codes with you.
