I wasn't satisfied with the current models of the airless basketball on here as they only had a single lattice. This took me days make sure the double lattice worked in CAD - SolidWorks was not built for this! As I don't have $2,500 to spare, I worked from the images available online.
GEN 12: This is the version in the video. I printed this in BASF TPC and then annealed it for 3 hours at 100°C. It is the closest I've seen to the original in bounce and durability. It's about 90% bounce and seems to be holding up to a lot of abuse. It cracked along the layer lines after a few days so I'd recommend annealing it for a lot longer than 3 hours.
The author remixed this model.
GEN 12: This is the version in the video. Print it in BASF TPC and you'll end up with a ball just like mine. I'd suggest using a different material for supports if you can as they were very difficult to remove.
