Stove Pipe

Downdraft is a nice design and works well for frying pans but they are not so useful for tall pots. 

This model can be installed on a Beko HIXI 84700 UF to bring the ventilation to the top of tall pots. A base is placed on the ventilation, and pipes can be put in the base, or stacked on each other. Inlets can be placed on the pipes to choose the side on which the fumes have to be extracted. There is also a lid to force more air to go through the pipes. 

Printed with a plastic that has some heat resistance, PETG works well. Use inside and outside brims when printing the pipes.
