Couldn't find a birdhouse I liked for our garden, so designed this one instead.

It's made from 3 parts, with the removable roof screwing on to the house body. 

A couple of notes for assembly;

It takes a little bit of effort to screw the two parts together. Take your time to avoid cross-threading. 

I added a tiny amount of super glue to the perch, just to avoid it rotating or falling out.

Printing

I found 0.16mm layers worked well to keep detail in the roof especially, and printed the roof and perch in Bambu Lab PLA Wood, and printed the body in Bambu Lab PLA Marble. Would love to see photos in different colours, as I plan to print some more for the garden.
