This not only looks cool but is highly functional. Each collum contains 9 storage carts. at the press of a button. the bottom cart is sent to the top, giving your base a SUPER compact storage room (wall :D). This is perfectly suited for underground bases. My current setup has a organization system; the block the button is attached to represents what types of items should be placed in the carts in that row. You can change this if needed. To have more carts in a collum, just remove the rails, and build the part touching the pistons a little bit longer, to heighten it. These can be placed next to each other indefinitely. Due to a North-South quirk, the rails might glitch up if the schematic is rotated. Have fun with it, improve it, whatever. No credit is needed, I want to see what the community can use this for.
