I have all sixty of the air pumps soldered to connectors and mounted on vibration dampening foam. Thirty are in a line on top 1 and 7/8″ apart, and the other thirty motors are mounted offset just below them. The connectors will allow easy motor replacement if one should fail. (A screw, an electrical connector, and a 1/4″ tube will need to be moved over to the new air pump.)

My super high tech vibration dampening material is simply 3/8″ strips cut from donated black rubber mouse pads.
