Combining Helicopter Robot Rotor Blades

A request from a friend, a set of replacement rotor blades for the Energon helicopter mould. Not sure how fragile it might be in Detail plastics, but the option's there. Tested in Black Detail, be prepared to drill or file out a little of the middle section in Detail materials in particular to fit the original toy due to print size variances.

EDIT: Recently this print has had issues with the Shapeways polishing process despite successfully printing until recently, so I've thickened it slightly to see if that helps but that's pushed the whole thing back to "beta"/"First To Try".

PLEASE NOTE: The connecting "ring" is quite fragile, so if you intend to paint the piece, please paint it BEFORE putting it onto your toy, as attempting to remove it again is likely to break the rotor piece.
