Dove birdhouse

This is the classic "Large Dovey House" design. We bought the smaller one years ago and the doves used it every year, having multiple series of birthings each season. I assembled using #10 x 1-½" wood screws instead of glue, so the doves aren't exposed to the glue odor. I also prefer 3D printing to building with wood because I'd have to paint or stain it to make it last and that might be a problem for doves. If printed in the orientation I show, you should require no supports. The screw holes are sized for pass-through for the first component and self-threading in the second component of each hole set.
