Conveyor Item Bag

The item bag can be attached to the side of any solid block or any conveyor machine. Items pushed into it via the conveyor system are stored in the bag. If the bag is full, the items will be "stuck" until removed or the bag is emptied.
Items will only enter the item bag on the attached side or sideways on one lane only (see demonstration below).

Items can be pulled out of the bag via hoppers or pipes, or accessed manually.
