My trusty Sioux 8030 close quarter drill suffered a failure of its cooling fan, cracked clean in half. I haven't been able to find a replacement part so far.

Does anyone know of a source? Failing that, it looks like a part that could be 3D printed, or use the old one to make a mould and then cast one. Anyone ever tried that or know someone who could do it? (I don't have ready access to a 3D printer) With casting I imagine any shrinkage or swelling of the resin used will result in it not fitting the splined shaft.
