How a part is turned before it goes in the box decides how many fit and for a complex, organic, or awkward part, the orientation that packs densest is almost never the obvious one. Pack Studio’s Optimal orientation searches the full space of 3D rotations, finds the pose in which copies of the part nest together tightest, so more parts ride on every truck, and each one costs less to ship.

Choosing a box is really an optimization problem that needs solved each and every time products or the components that make them get shipped. There is a continuous range of dimensions you could use, each one changes how many parts fit and what a shipment costs, and somewhere in that range sits a single cheapest answer. That is exactly the kind of search or rather solution - Pack Studio 1.10 should run for you.
