3 x 3 foundation with container and overflow output. Has input port, with an internal overflow container to not stop loading. Gathered overflow can be used from the back overflow port. Access door is on the front right. I generally distribute batterries at the receiving drone ports as they are usually several in a chain. There is an additional blue print for Receiving Drone Port which has battery access. The main difference is the configuration of the input and outputs and more decoration as the receiving ports are usually part of a factory.
