The UFO High-Inertia Spinning Top is a high-performance kinetic toy designed for enthusiasts who appreciate physics and precision. Its wide-diameter outer rim acts as a heavy flywheel, concentrating mass far from the axis to maximize the gyroscopic effect.

This version is specifically designed to be printed on its side, ensuring that the contact tip is incredibly sharp and the launching stem is structurally reinforced by continuous layer lines.

Key Features:

Optimized Gyroscopic Stability: Engineered to maintain balance and spin duration.

Sharp Contact Point: Designed for minimal surface friction and stable rotation.

Superior Strength: Side-oriented printing makes the stem virtually unbreakable compared to vertical prints.

Sleek Aesthetic: A modern, aerodynamic silhouette that stands out on any desk.

3D printing settingsOrientation: Print on its side (horizontal). This is the superior method for this model to ensure a razor-sharp tip and maximum mechanical strength of the stem.

Supports: Required. Use Tree Supports for easy removal and a cleaner surface finish.

Z-Seam Alignment: Set to Random. This is critical—placing the seam in a single line will unbalance the top, causing it to wobble.

Infill: 100% (Solid). Maximum weight is the key to long spin times.

Layer Height: 0.1mm or 0.12mm for the best aerodynamics and smooth finish.

Wall Count: 4-5 walls for extra rigidity.
