Kärcher K2/K3 attachments for cable winding and pipe storage

Needed a way to easily wind the cable for the Kärcher K2 pressure washer, it was just dangling around in a messy loop. Also needed a way to store the pipe when detached, so I incorporated it into one design.

I challenged myself to only use original mounting methods, so I utilized one of the two empty slots on the back that Kärcher uses to mount their own accessories. My model slots in perfectly and screws in with a regular old self-tapping plastic screw (like the ones Kärcher already provides).

Then I had to make a mount for the handle, and again, I didn't want to affect the original integrity of the pressure washer. So I 3d scanned the handle with Polycam and used that to shape a perfect snap-fit attachment for the cable. Then I decided to add a hook to it to hang the pipe of the pressure washer, there's a file for versions both with and without the hook. You can choose between "Kärcher cable loop on handle.stl" or "Kärcher cable loop and pipe hook on handle.stl" depending on your preference.

Material: PETG
Layer height: 0.2mm
Walls: 5
Infill: 15% Gyroid
Supports: Tree supports

With the above material and settings it is stronger than I'll ever need- the handle of the pressure washer will probably break before my attachment does (maybe, I take no responsibility for prints breaking).

I used tree supports because normal supports were incredibly hard to remove from the intricate part.

You will need a self-tapping screw for plastic, similar to the ones that come with the pressure washer, they are 21mm long, but I found that ones as short as 15mm still work. 

The mount for the backside is printed upright, and the mount for the handle is printed on its side, as per the pics below:
