Barrel Plug Cap

I have recently started using a 4s Lipo pack for my goggle power supply. In an effort to be cautious with all things LIPO, I made this cap to cover the plug. The likelihood if it shorting out is small, but with a 5 minute print, it's even smaller now. =)
I created two versions, one with a center pin and one without. Pick which one works best for you.
