I built my own Spacerail ball machine. I got my first Spacerail set on Friday, July 18th. I built the ball machine in the instructions that day. The next day, Saturday, July 19th, I designed, built, and filmed my own Spacerail ball machine. It uses 4 balls and has 1 track. Below are the pictures and video.
Spacerail ball machines remind my mom of Denha.
