Floating Ball Toy aka Flow Ball

An old children's toy which happens to be a good practice tool for playing a brass instrument, allowing a constant exhalation phase to be practiced. I use a polystyrene ball with a diameter of 3 cm.

Both models can be printed without support. Print the basket with the blow hole facing upwards and the pipe vertically upwards (if in doubt, use a brim for the pipe).

The pipe was not tight and too short for me, so I narrowed the connection on the basket and also increased the length of the pipe.
