It is also possible to add new block types to an existing AutoShulker, but you have to use a new book for the crafting recipe. If you want the box to behave like a normal shulker box again, just remove the book from inside the shulker box.
You are mining, but your inventory gets filled up with all those useless blocks like cobblestone, diorite, andesite, etc? Just get 2 or 3 shulkerboxes and have them automatically collect all that useless stuff! You inventory will now only contain all the fancy diamonds etc. while the useless stones will be collected in your shulkerboxes!
