The only Airless Basketball in Molten design that you can have. And the only one you may see online. Double wall same as the original Airless Basketball.
I printed it in small scale and tested. The original file is in typical size 7 basketball. I printed it with Resin and tested its durability and surprised that it is durable and bouncy.
