Venting Slot Funnel to install in Window / Door Frame (OpenScad, Optimizer, full parametric)

This adapter allows to install a venting tube to a small slot opening in a window frame or door frame. 

The CAD file is a full parametric OpenScad model, this allows to set many parameters with the OpenScad Customizer such as tube diameter, slot dimensions, wall thickness and much more.

I used this Funnel myself to dry a room with a side channel vacuum pump (Seitenkanalverdichter), connected with a 38mm vaccum tube to a 15mm slot in the window frame.

Several version for 25mm and 38mm tube and different slot sizes are included as STL files. In case you need specific dimensions, use Openscad with Customizer to adapt the model freely to your needs.
