I designed this stand for my son's first autographed Basketball. It fits a size 3 ball, but can be scaled for a larger or smaller ball.

Open in Bambu Studio and add the text to the sign, then color the text using the paint feature.

The profile will print by object so there is only 2 color changes during the print. If you scale the ball up, you will have to change it to print by layer.

No supports or brim needed.
