A planetary gear, but the sun is not in the center.

Yet another one of my experiments with gear designs (and I'm not done yet). Every gear has a different number of teeth, and the sun gear is not in the center (thus literally eccentric). Still, quite fidgetable.
Note: With a bit of force this model can be disassembled. Depending on printer, filament, settings and some luck, the force required varies, and for some the model even disassembled by itself. If it happens, you can probably reassemble it (the ring can be squished a bit to get gears in or out) and thus have some kind of puzzle, but that is selling a bug as a feature…
I added a version with tighter version with tighter tolerances.
You can also try the “binary sun gear”, it is eccentric, too, but more stable (and I find it even more interesting).
Printing: I recommend random seam placement.
