Bait Box Cover

In some summers this bait box is the only thing that keeps the ants away from the house. However, its design allows for rain to enter the box through the holes the ants are supposed to crawl into.
Since I can't control the weather I put together this cover in Blender. It fits the box almost perfectly. No rain can come in and the entryways stay open.

Note that it's a work in progress though.
