Glad they are working out for you. They are easy to make if you have a drill press. Drill a 1/2" hole for the umbrella rod. Drill #7 holes for the threaded holes and tap each one with a 1/4-20 tap. Use 1/4-20 set screws for the hot shoe end and knobs with 1/4-20 threads (or short bolts) for the umbrella tightening function. I used 1 inch square aluminum bar stock for the bodies (scrap stuff laying around in this case). Many metal dealers, scrap yards, etc have stuff like this. I also was able to use a bead blaster to make the surface look nice but spray paint would work too. I made 2 for me as well while I was at it. I haven't used them yet though.
Enjoy!
