For those people hitting a geo-block on the above link, this one worked for me in AU: https://www.youtube.com/watch?v=zRoHKpmcRS0

It's hard to tell from the limited actual bouncing/etc in the clip, but it looks like it's lighter and has less bounce than a regulation ball. Still seems to bounce crazily well for something 3D printed and without air pressure inside it.

I'd be very excited to see this become a thing for balls in general if they can make them even close to existing basketball/soccer/etc balls. I doubt we'd ever see them in professional sports for tradition-reasons but for amateur/home fun I think it makes a lot of sense and for that market they don't need to be "perfect".
