One feature. One simple part.
There might be multiple ways to solve this puzzle and I am always impressed with your creative solutions.
Warning! Spoilers ahead:
A simple extrusion makes this part. The "trick" to the puzzle is using a 3D sketch. Because the two profiles have the same thickness (5/8") the sketched profiles need to be separated by the same distance (I left one blue to make it clear). I've never had many practical uses for extruding a 3D sketch, but it works perfectly for this puzzle.

Hello all, here I post this challenge solution which I made with CATIA. One feature that wins this challenge is MultiPad
Let's have a look at sketch as defining correct cut to the curves play a major role on multipad feature.
Now let's multipad those open sketches. For this current sketch there are three domains- Inner circle; the left side bracket with semi circle; other semi circle. All we need is the first two and to define the extrude value.
This is how you make this part easily with very powerful multipad feature on CATIA.
I know you are kidding. I got the trick how to complete in one feature. :)
Ah. I was still trying to solve it as a single body model. 3D Sketch as a option did not occur to me at all. I then checked Fred's solution and it had 2 bodies. Nice puzzle.
