Depending on what printers you have available I'll put in the work to get you a ~0.02mm deviation scan of a blade off a 120mm noctua fan I broke. I expect it to under-perform notably due to the surface texture and the lack of rigidity under load causing contact with the shroud walls at high RPMs, but I wouldn't bet my lunch on it, would be fun to find out.

The texture has substantial chance to actually help. Check golf balls.
