Non-Stackable Bundle Slots
by kaffssist
Non-Stackable Bundle Slots lets bundles hold tools, enchanted gear and books, which normally cannot be placed in a bundle at all.
What it does
Each non-stackable item takes one sixth of a bundle's capacity instead of a full stack's worth of space, so a bundle can carry up to six of them. Shulker boxes can also be stored inside bundles. The mod is a server-side Fabric mod and works with vanilla clients, so players join without installing anything. It is released under the GNU Affero General Public License v3.0 only and is open source.
