About this 3D model

I just bought a Catalina 30' sailboat. Someone at some point cut an ugly hole in the beautiful teak bulkhead to run some cables through the boat, and I wanted to cover it up. It was a nonstandard size, but similar to a wall plate, so I created my own to fit over the hole. I will paint it the same color as the other fixtures on the boat and mount it this coming weekend.
