The Absurd Two-Planet Gear

A planetary gear with only 2 planets? Shouldn't that fall apart? The sun gear definitely can move sideways, but the assembly does not fall apart. This is indeed a strange thing - probably without any use other than being strange and thus somewhat interesting.

The hex holes fit typical hexagonal pencils.

If you like interesting uncommon gear fidget things, try the "binary sun gear".

Printing: The usual stuff works fine (0.4mm nozzle, 0.2mm layer height). I use random seams to avoid thick seam blobs though.

I uploaded 2 versions with different tolerances; the smaller one (tol15) should be fine with well tuned printers.
