Custom Bird House

A real nest box, 3D printed and sized to the bird: the entrance hole is the diameter the species needs (29 mm for wrens and chickadees, 32 mm for titmice and nuthatches, 38 mm for bluebirds — the sizing that keeps sparrows and starlings out), no perch, drainage holes in the floor, vent slots under the eaves, a wide-overhang gabled roof that lifts off for the yearly clean-out, and two keyholes on the back to hang it on a post or tree. Clapboard siding, and a family name set into the front in a second color. Songbird 110 × 110 mm floor, about 205 mm tall with the roof · Bluebird 130 × 130 mm floor, about 230 mm tall. Printed in PLA on a Bambu Lab P1S — hang it in the shade. Design yours at design.anoorai.com/bird-house.
