The Fan Spinning Top: Industrial Physics on Your Desk Most spinning tops look like vintage heirlooms. This one looks like it was pulled straight out of a ventilation system. Designed with the aesthetics of an industrial suction fan, The Fan Spinning Top combines high-torque visuals with a low-friction tip for satisfyingly long spin times.

The open-vane design isn't just for show; it manages weight distribution towards the outer rim, providing the rotational inertia needed to keep it upright even when your desk isn't perfectly level. Whether you’re a mechanical engineer or just someone who needs a tactile distraction during a long render, this print delivers.

Why download this?

• Unique Aesthetic: Breaks the mold of traditional "lathe-turned" top designs.
• Precision Tip: Optimized geometry for minimal surface friction.
• Printability: Designed to be printed upright to ensure the tip remains perfectly concentric and sharp.

Technical Print Notes To get the best performance and the smoothest spin, follow these parameters:

• Material: PLA (for rigidity) or PETG (for durability).
• Nozzle: 0.4 mm.
• Layer Height: 0.1 mm – 0.15 mm (Lower is better for a smooth tip).
• Orientation: Print exactly as the file is oriented (upright) to maintain tip integrity.
• Supports: Tree supports are highly recommended.

Pro Tip: If your slicer allows it, enable Ironing on the support interfaces for a cleaner finish on the underside of the vanes.
