Cyclone dust separator Karcher coupling

This is just Meshmixer merge of threaded hose adaptor for: https://www.thingiverse.com/thing:2018105 and Karcher "handpiece" side coupling: https://www.thingiverse.com/thing:3662734

Be careful to make sure it's the right one matching your vacuum cleaner, Karcher uses different types of locking mechanism shapes (I've seen at least three different ones). Mine is for 2019 WD5.
