Parkside Kärcher Adapter

I bought a Parkside pressure washer but still have the Kärcher accessories. Therefore, I designed an adapter for the lance so that I can continue to use the Kärcher tools. The spring is a bit soft and somewhat difficult to remove from the support material. A metal spring would be better, but it works. The O-ring for the Parkside connection has the size 9x7x1.5mm (I bought it). Due to stability and UV resistance, I printed it in ASA.

I hope you can use it.
