Đồ Chơi Bóng Bay (Bóng Lưu Thông)

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).
