Adapter Pressure Washer M22 to Elem Technic

You have to download the threads module by dan_kirshner and put threads.scad in the same folder to make it work.

There are 2 stl, one with an hex to help you fix the adapter, other without.
i personally printed the one without the hex, it worked well for me!

This project became from the purpose of connect a brand new Parkside Pipe and drain Cleaning set buyed at Lidl and make compatible with my old (very old) pressure washer Elem Technic.
My pressure washer have a lance with 2 thread starts ( two screw threads)
I buy an adaptor on ebay (see the pic) with this description:
