Interlocking Hook V2 - with bump (pintle and gudgeon)

I had a request based on my interlocking hook to add a bump as to hold items more securely into the hook. The open hook version is here http://www.thingiverse.com/thing:2279609

I bent one hook so you can see the pintle and gudgeon. (bump and hole respectively).

The intent of this project was to provide for a software learning curve. I am very impressed with Fusion 360, it is far more powerful than 123d and it is quite easy to learn.
