Basic 3D Wheelchair Cushion Model

I need an animated 3D model of a 3D-printed wheelchair cushion for visualisation purposes. I also want to include the WheelAir ventilation system connected to the cushion through tubing. I want the animation to include cool air blowing through the top of the cushion...
