There are people who are working on real 3d slicing software (where the nozzle actually moves in all three dimensions whilst extruding) which would allow you to print step free roofs. I believe it is only available on Linux at the moment though.
I think it looks fine now, near and tidy and no chance of splinters. A friend of mine who owns a garage and can weld always says he hates woodworking as he can't just tack weld and extra bit back on if he cuts the wood too short.
