EcoFlow Wave2 Front Intake Plate

I have created an adapter plate for the front intake of an EcoFlow Wave2; utilized https://www.printables.com/model/955300-ecoflow-wave-2-front-air-duct and https://www.printables.com/model/521583-ecoflow-wave-2-hose-takeoff utilizing tinkercad to use the large pipe for air intake. I am not overly familiar with 3D design so this design could likely be optimized some where I merged the hose takeoff and base adapter plate.
