Marble run

This is a marble run that I designed. This marble run features cams that pushes a track segment up. The segments are measured perfectly, allowing the marble to slowly go up. This is a really fun and cool design. I hope you enjoy watching the marble going up and rolling back down as much as I do.This design uses a motor, you can get it by clicking this link: https://e.tb.cn/h.Tnhz1NarBQxspNt?tk=KuGIeUZ1J3N
