Parameterized Bird House Roof

When the squirrels ate the pine-cone-tile roof off the birdhouse my wife and I made, we decided to replace it with a shingle/tile roof. It had a dowel top above two flat sides, so we needed a cap to keep the water off. A Python Blender script lets you specify the dimensions of the parts. Print two roof pieces and one cap piece. They are angled such that I was able to print them without scaffolding.
