About this 3D model

The original wouldnt slice right in Repetier V0.90C for me and basicly i would get the picatinny and not the gopro part when i went to print it, so i deleted some of the troublesome vertices and edges in 3DS Max and exported it back out and it printed fine. i also fliped it by 180° on the Z axis so that the GoPro mount is at the base, requireing little to no support material as opposed to printing it with the GoPro mount floating on the top like it was.
