Sand Duper 72k Per Hour (All Gravity Blocks)

This compact redstone machine is engineered for maximum resource output, capable of duplicating sand and other gravity-affected blocks at an impressive 72,000 items per hour. The intricate assembly of observers, pistons, and slime blocks creates a repeating cycle that automates the collection process. Designed specifically for technical survival players, it fits within a small footprint without sacrificing throughput. It represents a highly optimized solution for large-scale construction projects requiring vast quantities of sand or concrete powder.
