This housing is for the standard 2-Prong body cords primarily used in the USA for Foil and Sabre. It's best use is for saving cost while repairing club equipment. The cost to print both sides is about $0.17. I would not compete with this design nor any other 3D printed plastic fencing parts.
For the clip, I'd personally recommend just using one that came with a Favero body cord. I designed it for the bendable kind, not the kind with a spring. The file I included will work, but it's life limited. It's finished, but I'm not satisfied with it. If I come up with a new design, I'll update the file to reflect the change.
Note that because I decided to make both prong holes the same size, the actual prongs are a little loose. Don't be alarmed. They're secured and pulling on the housing won't strain the wire.
I've assembled this onto one of my body cords and intend to test it over the next several months (start date 2/10/2019).
