Is this model intended for a D/F setup or small Turbine? My Gold 44 would fit perfectly in there

This would also make a nice size EDF for the Stumax 110mm fan.

I saw this and thought I would reignite it. I currently have the plans at a laser cutter and he is finishing the files to cut. I am stumped on sheet 5. What are these parts, where do they go and what are they cut from? I came across these plans and can never find an arf or like thats affordable, so I decided to give this a shot.
