You can get fair results cutting replacement foam with an electric meat carving knife. :) Inexpensive ones sell for less than $20, like this one:
Davis plastic sextant cases are notorious. That blue packing foam they use, soft and pliable when new, eventually becomes stiff and decays into blue plastic confetti. I've "repaired" three such cases so far with a strip of foam from Home Depot (maybe $10) and one carving knife, as above.
