Kärcher WD to DN 50 Adapter

thingiverse

With this adapter, you can easily attach a DN 50 HT pipe (or in my case, a DN 50 aluminum hose) to a Kärcher WD 3 multi-purpose vacuum cleaner. This adapter should work with all Kärcher vacuum cleaners that have the same suction connection system. I connected my Kärcher to a cyclone and wanted to minimize loss of suction power, so I used as much of the available diameter as possible. Since both the Kärcher and the cyclone have 50 mm diameters, it made sense to design an adapter that would allow them to be connected with a flexible aluminum pipe. The click-in mechanism is not perfect yet, but for my purposes, it's sufficient. If you want to improve this design and make the mechanism work more smoothly, feel free to remix it! I'd love to see your improvements. If you need something for the other end of your suction system to connect a Bosch "Click & Clean" device, take a look at my adapter for that: [Bosch GCM to DN 40 Adapter](https://www.thingiverse.com/thing:4063624).
