Basic mount for a Karcher WV60 window vac.
Caution: the STL is quit big,
I recommend you use repetia host, to view the layers, after slicing,
because Slic3r might fill every thing !!
settings are crucial,
I sliced with: remove unnecessary fill, and at 40%
and 3 wall's
Note, there is a bit of an overhang !!
I have just invented an interesting solution for this !
see the photos. :)
