Comparison

The jump up from a half sphere seems quite a lot but lets figure out how much.

Half Sphere =

  1. 6 Pentagons
  2. 5 hexagons
  3. 5 half hexagons

The most recent version is

  1. 15 hexagons
  2. 11 pentagons
  3. 4 half hexagons

So 16 parts verses 30 parts is virtually double. Add 6 half spheres and another pentagon for a full sphere.

I wonder if it’s more prudent to ship each ‘full’ sphere with a spare panel of each type for spares. This could be a possible stretch goal since it doesn’t take much in extra effort.
