About this 3D model
Made a newer version of my exhaust port adapter, it's slightly heavier duty. Uses three 16mm magnets to hold it on the back plate. Also found a perfect fit 3 in 1 carbon & hepa filter that fits inside if you want to use it with or without the hose it just adds an extra layer of filtration.
