Thx guys. And sorry, it's not my intent to make and sell it, more of out of self enjoyment and sharing the idea.
As Curtis mention, it's pretty easy to find the parts and make it yourself. I think the hardest part is that not everyone has a set of tap and die at home. My original plan for the cold shoe part was to take the old one off the old bracket and screw it on the steel bar, but I couldn't get those 3 tinny screws off, so ended up cutting the whole end off. Otherwise it would look more nice and compact.
I am still working on the finish of the bracket, may even try to paint it. As soon I am done, I will show all the small parts involved.
And yes, the tripod is a Slik 300.
