Shulker Loader Small
Idk I kinda stumbled on this build in my Redstone ideas world. Cool concept, kinda hard to pull off as we need a LOT of shulkers, but if u can build a shulker shell farm (which I didn't have when I replicated it in my survival server and had to buy a ton of shells for not so cheap) it turns out to be pretty good especialy if your moving a load of items in a chest minecart system. I might build one of those soon to explain the theory.
Build It
Go to my 2 X 3 piston door to get help, I rlly don't wanna put it again
