John,

I will happily print any fan .stl file you provide.

There are some on thingiverse that are scaleable.

John Rudd:
Charadam,
 
Thanks for the offer....unfortunately I cant do stl files, dont have cad....

Looks like I'm going to do some metal bashing...with some al sheet.

WeldingRod:
Can you take a picture of these fans?

As requested....
So the first is the silicone mold used to mold the new resin fan, next is the steel bush insert, this sits in the centre of the mold and has the resin cast around it, it then strengthens the centre of the fan.
Next is an aluminium fan machined from solid....finally, two fans, the one on the left is the cast version, the right one is an original
