Karcher parking nib fix

I've designed a part that fixes problem with broken Karcher WD2 parking nib.

It's designed to be printed upside down with minimal support (required only on horizontal overhangs).

When done - you should be able to slide it in position and then rotate. Remaining of original parking nib are preventing it from sliping up/down. You can either print it a little smaller / anneal it or heat and bend inwards / or use zip ties in order to make it more tight. Maybe it could use some glue, but I haven't tried it.

The nib is a little bit longer (for easier printing) and a little bit lower - As new nib isn't positioned in the middle of the nozzle bend, the nozzle is resting at different angle, and requires to be a little bit higher in order not to touch the floor.
