Simple single item type smart 3D expandable(can expand in all 3 directions) 3WT

Credits: design and concept by @twiti888 Help from Burnt torch in earlier versions Top hopper line wiring concept by lintex Pros -Fully hopper locked, except for input hopper -expandable in all 3 directions -only single slice(3 wide) unlocks when item passes through system -overlfow detection, which permanently locks the slice(3 wide) -noteblock for unlocking the permanent lock -lever for global locking and unlocking -compact design -13% more dense than cubicmetre's bulk concept -works in all dimensions (can use water/piston+slimeblock) -Toggle stateless Cons -uses dust, but almost all dust is ss1 Things to point out -intended input is shulkers -can have issues if input has stacked shulkers -it can savestate, so be careful with number of chests in single chunk -master chest is where all the items from all the slices end up into Schem provided is 21mil but there isn't hard limit other than world border, world height, your potato computer <-- biggest limit.
