This is a hose/duct adapter for those plastic/aluminium hoses you get for standing aircons, to vent outside a window.

I used a hose to vent my 3d printing enclosure.

This adapter is used for hanging the duct out a tilted window like the ones in germany.

I printed my model with 4 walls for more stability and 15% infill in PLA (PETG would be better)

Differences to origin:

I designed a completly new adapter based on the original authors work.

I changed the diameter of the round part to a smaller size to fit my hose  a bit better.

I also changed the sizing of the box part in the front and the sizing of the hook things on the side. In my version  the box is not as wide as the original so it would fit the size of my window.

Furthermore i changed the part that connects the roud base part with the box part (different curvature, etc.)
