Alternate Suction Head for attaching a Zimpure Air Purifier to the SE300 hot end

The tubing is made by Sunset Healthcare solutions. You can get one on Ebay for about $8. See the photo of the label. It only weighs .3 grams per centimeter, compared to 1.1 grams per centimeter for the stock silicone tub
