Planetary Gear Pumpkin/ puzzle

thingiverse

Planetary gear bearing meets pumpkin. Can use as a fidget spinner or puzzle. The design is print in place so does not require any assembly. Current version has a truncated flat base for easy printing without supports. The design makes for an interesting visual appearance when the gears are rotated away from the starting position. It appears to take 26 full rotations of the outer ring with respect to the inner (Sun) gear to get back to the starting position - so the design can also act like a puzzle to try to get back to the original pumpkin shape. The natural creases/valleys on the top of the pumpkin shape serve to also confirm if the original position has been achieved. After randomizing the position of the outer ring (by spinning) it may take up to 26 turns to get back to the starting position (well formed pumpkin). Need to slowly turn the outer ring while carefully observing if all the valleys are lining up. The current version has a clearance setting of 0.2mm which should print with minimal binding on a well adjusted printer. A hex key socket (6.7mm - standard driver bit size) is provided on the base of the central sun gear to aid freeing up if needed.
