UPDATE: check my profile for the newer GEN 11 model

THIS WILL BREAK IF PRINTED IN PLA, PETG, ABS OR PA!

IT WILL NOT BOUNCE IF PRINTED IN TPU!

I recommend my latest model (found on MakerWorld) printed in BIQU PLA-HR, DUDV2 PLA-B Splat or Sting 3D's FPLA+.

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.

I have uploaded a version with no holes round the middle as requested

MATERIALS I'VE TESTED:

Extrudr Hard TPU (58D) - good durability about 40% bounce
Overture Super PLA+ - 100% bounce but broke easily
Overture easy nylon (PA6) - broke almost instantly (the community have suggested \u201cannealing\u201d the print in water to increase durability)
BASF Forward AM Ultrafuse TPU 64D - good durability and 60% bounce (BEST SO FAR)
