Oh this is interesting:

> The two primary exterior plastic parts are huge, detailed injection molded parts with multiple slides and actions, large changes in wall thickness (which makes it very hard to mold without imperfections)

Does anyone know why large changes in wall thickness makes molding these parts more difficult?

Molding parts with uniform thickness is tricky enough - without great tooling design and the perfect temperature/pressure settings, you'll get hot spots, flow lines and all sorts of visual defects in your part. Varying thicknesses make achieving these "Apple-like" levels of perfection in the plastics even more difficult, thanks to the fact that the material will cool and change shape at different rates.

Oh that's fascinating - thanks!
