This unique fidget spinner combines satisfying tactile play with an elegant planetary gear system. It features six planet gears that rotate smoothly around a central sun gear, all housed within an internally toothed outer ring.

The double helical gear design ensures exceptionally smooth, quiet operation—no bearings required. Whether you're looking for a cool tech gadget, an educational demonstration piece, or a relaxing fidget toy, this model delivers both function and style.

Print Recommendations:

• Layer height: 0.16 mm
• Perimeters: 2–3
• First layer compensation: -0.1 mm
• Seam position: Random
• XY outline compensation: -0.02 mm
• Ensure the print bed is clean and degreased (e.g., using isopropyl alcohol)
• Due to tight tolerances, minor post-print movement may be needed to free the gears

Note:

• Prints as a single piece — no assembly required

Tip:
For even smoother spinning, apply a small amount of light oil to the gears.
