92mm fan blade replacement

replacement fan blade assembly for a 92mm fan.
one of the welders at work was missing 2 fan blades so i knocked this up to get it going again. blows a heap of air. may need to scale it to suit your application though.

just snap off the remaining blades and file smooth and slide this over. Glue if necessary. It was a perfect interference fit for my application. ID of the fan ring is 46.8mm with 84mm fan blade diameter.
