About this 3D model

Inspired by the tin can bird house, http://www.thingiverse.com/thing:20851, I thought, I`d like a birdhouse in my tree. I have a Thing-o-matic, some plastic, and I`m not afraid to use it, so here is my bird house. As I'm limited a bit by the build platform, the house is quite small, but the entrance hole is suitable sized for blue tits ( from the RSPB website) and it has a drain hole at each corner.
