Earth rod cover

A friend has a house with the mains earth (ground for those in the US) provided by a metal rod in the ground (TT earthing system). Due to the action of weather and cats rubbing against it, the wire connected to it eventually fractured. So after the connection was re-made, I printed this cover for the rod and the clamp that connects the earth wire to it. The small holes are to allow a cable tie to be inserted, below the clamp, to secure it in place.
