shore cord plug for Casita

Casitas and other camping trailers use a heavy cord for shore power that is hard wired to the trailer, coiled in a cubby for transit, then pulled out to connect to the campsite power post. A hole in the cubby door is provided for the cord, but it is larger than the cord, and in certain environments allows critters/bugs to get into the cubby. This thing closes up that hole, fitting close to the cord diameter and the door hole. It is printed as two pieces that snap together to form the hinge that fits around the cord.
