Description
I designed this for a Parkside wall-based vacuum sucker to be compatible with my Kärcher NT 70/3 Me Tc vacuum, that uses the thicker DN40 (40mm ID) standard instead of the DN35 found in household vacuum cleaners.
I recommend deburring the sides of the adapter, as they can be pretty sharp after being printed.
