Hook for keyhole mount (Q59349)

I combined the ancestor hook idea with the self threading bolt idea from http://www.thingiverse.com/thing:15322 This allows the hook to lay flat for easy printing. I also added some curves for strength and aesthetics. The hole is .125", so a 6-32 machine screw will self thread when screwed in. 2 screws required per hook. You will need to make sure the hole spacing fits your application.
