I recently found narrow divider feet hidden inside a case. Our FR5 pallet drawing still treats the entire bottom as support. What cheap comparison gets packaging and tooling looking at the same problem?
A section through two loaded layers, with those feet and the tool fingers shown. I'd start there, though packaging will have to decide what support the carton construction actually needs.
That view exposes two feet over gaps. Tooling wants wider gaps for finger release. I have put both drawings into one review instead of accepting either separately.
