Ball blowing training game, breathing training. You have to blow so that the ball is in the air and does not fall outside the basket. You need to print the "blowpipe" model. A layer height of 0.2 mm is sufficient here. You can print the attached ball model for this. The ball must be as light as possible.
Here I recommend a layer height of 0.16 mm. It is best to use a polystyrene ball (it is very light) plus or minus 32 mm in size.
No supports are needed.
The author marked this model as their own original creation.
