While I'm not a little person, I've somehow managed to hit my head a couple of times on the bottom of that toothed gear. Please don't ask me to describe the stupid/clumsy things I do in my garage. It usually involves power tools and/or lost screws and washers.
What is that little hole on the end of the gear supposed to be for, anyhow? I figured I would put a flag or pull-chain on it to remined me to keep my numbskull away from it, but I rescued this little charm from my old Xterra before I sold it, and thought it should find a new home attached to the TLP. It's not easy being green.
I think it's an appropriate charm given how Yoda first demonstrated his power by lifting things.
