Printed option C, which is the larger in 2 parts. Still isn't that large, but there's probably an optimum width of the bit you grab to make it spinnable. It's a little try to get spinning on its end, but with a bit of practice you get it without flinging it around the room :)
To get the bits to fit together I had to use a router to remove some of the remaining support structure from the top part, but when I did it fit snugly without glue required.
