I was fortunate enough to pick up an old but well loved egg beater drill from a flea market. I use it occasionally and I cherish it.
It got me thinking what MetMo's take on one of these might be, and how you might apply your design style to reimagine it as a tool and fidget toy.
I have visions of being able to take it apart and reassemble it Transformers-style into a spinning top using the handle, the large gear wheel, and the chuck. It would be especially cute if the drill was scaled down to begin with.
