[title] 3D Parts
[* black] Halo and its fittings are made via 3D printing. The halo, fan mount and air connector blocks remain inside the bag and are reused after cleaning
[* blackicon_note] Bag penetrator and flutter valve fittings are outside the bag and must be replaced or sanitized between uses. Soak PETG parts in 99% IPA if unable to dispose between uses. Ideal is to print enough penetrators so they can be single use.
