Doesn't look to me like a fixture is really needed for that part. Cut them from a strip of material, and leave tabs at either end that you remove after machining. Or, make a very simple fixture consisting of a plate with a series of threaded holes. Clamp the raw stock to the plate, then mill the internal holes. Then insert "plugs" roughly the shape/size of the holes, and bolt them down to the plate. You can then mill the entire outer profile - on the first pass, leave about 0.050" at the bottom to hold everything secure, and take that off with the finishing pass. I do lots of parts that way, many of them much larger than those.
