Re shaped parts for a better base-spinning Gear Heart.

I had some difficulties after printing this model:

Had to design some parts on my own for different reasons:
1) Some pieces when placed into position made other pieces slip out so I designed pins with longer "thin" part.
2) I had some friction so the original shape of the handle didn't work for me.
3) I also had to make the handle gear bigger.

Hope you find it useful!
