WL Toys v912 tail rotor protector fin

I honestly don't know what to call this thing, it protects the tail rotor on my buddies RC helicopter when he lands. He keeps breaking them so asked me to print him a couple.. So this is the end result. I'll add pictures later. I created it in fusion 360 and printed it on my borlee prusa I3

This is for the v912 by WL Toys.. If you have the brushless motor upgrade you need this one.. http://www.thingiverse.com/thing:1064415
