There’s some friction between the parts, and the inner sphere almost never prints perfectly round. But that’s not really the point. It’s more about tactile interaction than smooth, continuous spinning. \u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eYou could theoretically print the outer shell in two halves and the inner sphere separately (also in halves) using variable layer heights for a smoother result, then glue everything together.
