Sikorsky UH-60 Black Hawk inspired rotors 1/400

People have requested some of my older Transformers custom toy rotors be rescaled for smaller Helicopter models but they felt too toy-like so I made a set based on the Sikorsky Black Hawk. 

Echoco doesn't include rotors with their helicopter models, which I appreciate because at 1:400 scale they are tiny and fragile. On request, I've tried to create some which are thickened up in places to make them printable, so some liberties were taken. Be warned, these are likely still EXTREMELY fragile due to thin parts in places. Exercise extreme care when removing them from the supports. 

This set contains 8 rotor parts.

I don't own the original Echoco model so the rotors are likely to be loose on those pegs, but they should at least go on and then give you the opportunity to add glue/putty to your liking.
