The sphere has just enough room to move freely inside, allowing you to spin and rotate both the sphere and the octahedron in a few different ways.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eFor the best visual effect, I recommend using dual-color or tri-color silk PLA, or any co-extrusion filament, to really make the sphere and top\/bottom layer patterns pop.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eThe included print profile has all the recommended settings already dialed in, so I strongly suggest using it to save time and ensure the best result.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eIf you prefer to use the STL files instead, be sure to center and merge the sphere and octahedron in your slicer before printing. You’ll also want to adjust the settings for each part individually. I’ve included two versions of the octahedron: one with a Hilbert curve pattern and one with a simpler top and bottom. Feel free to choose whichever suits your style.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eJust a heads-up: don’t expect long spin times. There’s a decent amount of friction, and the sphere almost never prints perfectly round. That said, it's still a super satisfying little fidget toy to mess with. It’s more about tactile interaction than smooth, continuous spinning.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eIt’s worth noting that you could theoretically print the octahedron in two halves and print the sphere separately (also in halves) using variable layer height for a smoother result, then glue everything together. I haven’t tried this myself, though, since the goal here was to make something print-in-place.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePrint Settings I Used (Bambu Lab P1P):\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e•\u003cstrong\u003e Nozzle:\u003c\/strong\u003e 0.4 mm\u003cbr\u003e• \u003cstrong\u003eLayer Height:\u003c\/strong\u003e 0.2 mm\u003cbr\u003e•\u003cstrong\u003e Infill:\u003c\/strong\u003e Octahedron uses 10% gyroid, sphere uses 5% gyroid\u003cbr\u003e• \u003cstrong\u003eSupports: \u003c\/strong\u003eOctahedron doesn’t need supports, but the sphere does (included print profile only adds supports to the sphere)\u003cbr\u003e• \u003cstrong\u003eTop \u0026amp; Bottom Patterns: \u003c\/strong\u003eOctahedron uses Hilbert curve, sphere uses Archimedean chords\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eIf you want to turn it into a “rolling octahedron,” try printing the sphere with a heavier infill percentage, around 50 to 100 percent. I haven’t included print profiles specifically for that, but it’s an easy tweak. On the other hand, if you want better spin performance for fidgeting, go with a lower infill around 5 to 10 percent.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003eIf you have any questions or run into issues, feel free to reach out.
