Started: June 2020 Completed: June 2020 Released: June 2020 A improved model of the spiral lift I made before. The pillar that supports the rotor was made as thin as possible. The shape of the receiver has also been improved, so that the ball does not remain. Switching the exit lane direction of the spiral path, the machine can be used as a Independent ball machine or as a Great Ball Contraption (GBC) module. I don’t make instructions for this model at this time.
