End for Modular Terminal Strip

I had salvaged some long modular terminal strips and wanted to use the terminal blocks in different configurations on the rail. In this particular case, each block comes with one end always present, and it is always the same end. The whole unit contains as many of this end as there are blocks, but only one of the other kind of end, at the end of the whole block. Many of end type one, and one of end type two, if that makes it more clear. If I was going to break up the one set of many terminal block units, so as to use them as more complete units of fewer block units each, to further clarify :) . If you have this same problem, you will already understand the situation, so I don't see any point in trying to clarify further. I know, a picture would be worth a thousand words. But I have no camera handy. I built the model in FreeCAD. I know it can be a struggle to figure out how to use it. It is not difficult once you know. I include the FreeCAD file in case anyone would find it to be of use
