Hi Brian,

> For 6 leaves, there is not enough latitude circumference, until 60 degrees from the equator is reached.
At this angle there is zero space for the hinge pins.

> At 61 degrees, there is only 0.0923 cm of room for 6 pins, which is extremely little.
The opening in the top of the sphere is small.

Sorry, I have difficulties to get what you exactly mean? Could you add some shapes for better elaboration?
