I am developing a small mod called 'Biter Spires' that adds alien structures to biter bases. These structures yield free energy when connected to the player's energy network, and they are unobtainable and indestructable (so they can't be moved). However, I am bad with graphics, so I kindly ask if someone could make a graphic for me. The only requirement is that the style should be similiar to that of the biter bases. The structure itself shouldn't have a higher width or length than a single spawner, but the height can be greater.
Right now I am using the accumulator as placeholder:

I thought about something like this (a Red Marker from the Dead Space game):
