Thingiverse user Mr_Megatronic has designed and printed this awesome birdhouse for the Thingiverse Birdhouse Challenge. It’s initial size would be suitable to house smaller birds like finches, blue-jays, chickadees and sparrows, however like most prints it could be scaled to suit.
The birdhouse has two entrances and is ventilated through the chimney and windows. It has sloping drains to let the rain run out and areas for the birds to shelter in. The house can be mounted with two large screws and is supported by two decorative trusses.
