Cable Y Splitter (Headphone/Microphone)

A housing to hide the solder connections between three cables. This has been sized for standard 3.5mm headphone/microphone cables, but may work for other cables as well. 

Print two of the included model - it's designed such that it will snap together with a copy of itself. The friction fit from the pegs is likely secure enough on its own, but you may want to use epoxy or hot glue between the two halves for additional robustness (and to serve as insulative potting between your solder connections).
