From Pixelmon Wiki
Great Ball lids are used to make Great Balls. To craft Great Ball Lids, cooked blue Apricorns must be placed on the outer two spaces and a cooked red Apricorn must be placed in the middle of the crafting grid. Two Great Ball discs will be obtained.
Using the discs with an anvil and a hammer will make them into Great Ball lids. These lids can be used to make Great Balls.
