It is a toy that blowing through a tube makes a light ping-pong ball levitate
Both pieces can be printed without supports if the hoop is rotated 180Â...º.
After printing both pieces should be press fit.
I have added a plastic tube obtained from a siphon bottle so that it can be easily replaced since this part is the one that is inserted into the mouth to blow.
I bought the ping pong ball from the Chinese. It is a little smaller and weighs less than the regulation balls which favors that it can be levitated easily.
