This is the airless basketball. It is one of the most difficult things to print due to the very top being printed with nothing to grip on to. It take 70 hours to make. One whole wheel of special and expensive airless basketball filament is used to make this. It also needs its own new buildplate every time you make one. This is by far my favorate thing ive 3D printed. It bounces like a regular basketball, hase the same wieght and is the same size as an NBA  basketball. Shooting feels great as well. This product will take about 3 weeks to ship, and in total costs about 70 dollars to make. Comes with stand as well.
