door 3*3 lever

This compact Minecraft build showcases a functional 3x3 piston door, smoothly opening and closing with a simple lever activation. Its balanced design integrates redstone components effectively around the central opening, creating a flush entry point. The exposed redstone wiring, utilizing a mix of observers, droppers, repeaters, and comparators, demonstrates a clever and relatively compact mechanism for a door of this size. Ideal for base entrances or hidden passages, it offers a reliable and aesthetically pleasing solution for vertical block retraction.
