This BallRun sample mainly demonstrates the use of U Shaped Tubes.

We used 12 U Shaped Tubes to create a spiral structure (three sets horizontally on the front, three sets vertically on the back).

U Shaped Tubes can achieve a 180° angle for ball movement,

creating a visually impressive effect as the ball rolls through the tubes.

Additionally, for added stability when stacking, we used basic square tiles as supports.

Overall, it's not a very difficult structure to build,

give it a try!
