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. I'll keep updating the page as I work on new designs.
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).
Use 3 perimeters/walls to ensure strength. This part may be hit by another fencer. Do not expect it to survive. I encourage using 20-50% infill with gyroid or cubic infill if you have it.
The holes for the prongs are identical on each side. The parts, however, are marked to show which prong goes where. The smaller prong will align with the S and the larger prong will align with the L.
Use 1x M3x10 screw for the lower hole and 1x M3x16 for the second hole with the clip. Use both screws and their respective nuts to secure the two halves together while making sure the wires aren't pinched and the banana connectors are in the right slots.
You can buy the appropriate set of screws as a kit from Amazon for less than $10.
I said you didn't need to use supports on this print. You don't. However, using supports on the build plate will increase the quality of the nut and screw holes, but will require additional post processing. I don't think this is necessary, but it's an option.
