-: The shape of the Base Foot is rectangular with a small circle cut out off-centered from the middle. In the Base Foot when you remove the base springs there are an additional two circles near the ends of the Base Foot. The Base Foot is three-dimensional and is axis-symmetric. This component’s shape provides a solid base for the fluid pump to be placed upon. The Base Foot’s width is the same length as the water pump that provides stable support when the product is in motion.

 :''' Material: '''
 : The Base Foot is made out of steel which is material that can be effective, cheap, and durable. This component must be durable enough to handle the amount of force the water pump is generating. The Base Foot is connected to the springs on opposite ends which are also made out of steel. It must be durable enough to withstand the force of the spring attached to the water pump.

-;[Die] Casting: Metal casting process characterized by pouring molten material into a [steel] mold comprised of at least two dies. The molten material then experiences high pressures to take the mold’s shape, and then is left to harden. Process is cheaper than investment casting, which is only needed for very detailed components. From our component analysis, we concluded all cast materials to be manufactured by means of die casting. '''Evidenced by:''' ''Parting lines; Smooth yet uneven finish; Non-magnetic material (typically)''

 ;Injection Molding: Produces plastics and other polymers. Plastic granules are melted, and commanded to take shape by being forced (due to their low fluidity) into a metal cavity, where they are left to harden. The cavity is shaped in the desired material profile. '''Evidenced by:''' ''Plastic or rubber material (polymers); Parting lines''
