Còi Turbo trên Vòng bi

A little turbo whistle on a 22mm ball bearing. Kind of need some big lungs to get it going fast but does make sounds at lower speeds too. Here is a link to the ball bearings that I used. https://www.amazon.com/dp/B0G34JLXLK?ref=ppx_pop_mob_ap_share&th=1

Below is the deminsions of the bearing and the parts of 3D print that it fits in to respectively.
