My son and I designed this birdhouse to print as a single piece. It just fits inside a P1S printer and can be printed with just tree supports originating from the platter only. It will fit atop a standard 5"x5" PVC fence post. The bird hole is 1.75", which I read is appropriate for finches and sparrows. I just put it up on the fence and I'll update here if birds move in. IF YOU DOWNLOAD AND PRINT THIS, PLEASE SHARE A PHOTO OF WHERE YOU PUT IT AND ANY BIRDS THAT MOVE IN. WE'D LOVE TO SEE THEM!
