End parts for cable chain

I had originally used this chain by eddiema but needed max 17mm and the scaled down version was not so good (too loose). Then I found this version by Codiacx https://www.thingiverse.com/thing:511938 but there were no end parts. Hence I used the end part designs from eddiema but made smaller. very complicated but there are many similar designs!
I include freecadfiles in case anyone wants to modify.
My thanks to Codiacx for sharing this version!!
