Pipe Tool

Conveyors, crafters and storage adaptors sit there doing nothing until a pipe joins them, and this is what lays the pipe. Aim at an object, click its output handle, click the next object's input handle, and the link is made.

Picture the first evening of an automated furnace yard. The ore box gets a storage adaptor, a pipe runs from it to an industrial conveyor, another runs from the conveyor onwards, and an industrial splitter fans one line out into three. Your first try at that route will go wrong somewhere. Holding the right mouse button clears or cancels a connection, so a misclick costs you nothing but a second.

Three tools look alike and carry different things. The wire tool carries power, the hose tool carries water, and this one carries items. Each costs two HQM at a Level 1 bench and every player knows all three from the start, so craft them together the day you start on the engineering side of the base.
