Alfa 166 water pump impeller

thingiverse

Replacement impeller for an Alfa Romeo 166 water pump impeller (year 1999) 3.0 V6. I printed mine using Taulman Nylon 645 (and would expect that any sane person would do the same - it is pretty much the only suitable plastic to use in this application). Use this at your own risk. It may need some tweaking of the spline. Mine was an extremely tight push fit once printed (needed a vice to fit). Unfortunately, I do not have the source files in a common CAD package.
