Description:
A stylish fidget spinner combined with a functional planetary gear system. It features six planet gears rotating around a central sun gear, all enclosed in a ring with internal teeth. The gears are double helical, which ensures smooth and quiet operation — no bearings required.

Print Recommendations:

• Layer height: 0.16 mm
• Perimeters: 2–3x
• First layer compensation: -0.1 mm
• Seam position: random
• XY outline compensation: -0.02 mm
• Make sure the print bed is properly degreased (e.g., with IPA)
• Due to tight tolerances, some post-print freeing of parts may be required

Note:
Prints in one piece — no assembly needed!

For even smoother spinning, you can add a few drops of oil to the gears.
