Birdhouses for scale modelling

We were looking for a birdhouse to add to a fallen tree on the wargaming board we're building. I could only find real birdhouses, which are obviously hollow, so scaling them down would not work.

Instead I quickly designed these, intending them to be 28mm scale but I am just off to print them now to see how they turn out. however feel free to scale them to your needs.
The bird feeder was added at the last minute for fun, there is no wire mesh or texture as at the scale I intend to print it, the texture would not print well. That would need to be painted on.
