Eastern Bluebird House

I made this birdhouse to replace our current one that is beyond repair. We have been getting up three clutches of Eastern Bluebird eggs each year with the existing house. I researched house designs for Eastern Bluebirds when designing this house. The one criterion I did not follow was the outside perch. Our current house has one so I put one on this house. I have included plenty of ventilation and drain holes to keep them cool and dry. I recommend using PETG or similar material that is resistant to the outdoors and sunlight. My print profile includes a modifier to create a texture on the top of the inside shelf to give the fledglings some grip to climb out. I recommend calibrating your filament due to the tolerances for the assembly clips. They are a tight fit and not really meant to be removed. [UPDATE 4/18/2026] - We have already had one clutch of eggs hatch in the new birdhouse. It looks like another pair of bluebirds are getting ready to lay another. The house has been up for 4 mon
