Cap for NEMA L14-30 plug

A cap to protect the pins on a NEMA L14-30 locking plug. This kind of plug is commonly used on emergency generator cables. (or, in my case, a charging cable for my Volt!)

I designed this because these cables and plugs spend a lot of time in storage where it is easy for the pins to be accidentally bent or damaged. It fits pretty well on the 2 plugs I have, but it seems like there's a fair amount of variance among different plug manufacturers.
