Replacement knob and foot for camera tripod mount

I broke the foot off the special bolt that holds this mount to the side of a tripod and ended up buying a new one. However while cleaning things out I came across the old one and realized it was repairable. You can guess which one in the picture is the one I repaired, heh. It would have been a 20$ savings. I'll probably give the spare away to a friend. I am posting this here as an example of what a 3D printer can do that is useful when your wife/husband says "Ok, it's neat, but what's it GOOD for?". And maybe the files will be useful to someone else somday, who knows.
