I modified the original author's ball circle and made it invisible.

This is a lottery type model.

When you rotate it clockwise, it can run out one ball at a time.
However, if you rotate it counterclockwise, the ball cannot come out (it can be used as a cleaning ball).

Print content:

1. The file contains 50 balls (you can change the printing color at will) (he first prize)*1 (second prize)*2
2.The ball enters from the left
3. The left/right side of the lottery machine ball circle needs support when printing.

I hope you guys like it and have a great time.

The model is printed using PLA. (3 layers of walls, filled 15%, using layer height 0.2mm)
If you want to increase the anti-fall strength, it is recommended to use PETG for printing.
