Since I cant purchase 50mm PVC in the US, I mocked up a tube that would fit in its place as well as added legs to the end cap so that it can be a ball dispenser too.
The tube is in two pieces to fit in the print volume of a Bambu Lab P1P. The two piece design should fit a dozen balls.
The author remixed this model.
I used the end cap from chocarrat's design and the legs from the basket-o-sass design.
