Based on BlockerLocker's Barrelporters commands.

This datapack(mod) adds ender barrels to the game which are like little item portals. drop a ender eye and a ender pearl on a barrel they turn into a sender and a receiver barrel. put an item into ender eye barrel and watch it teleporting to the ender pearn barrel. you can point a receiver barrel with multiple sender barrels. also you can rename tha barrels via anvil to link them by name
