No perch under the hole (for predator safety)

Interior climbing ridges for fledglings

10 mm thick walls for insulation

Rounded egg-like shape helps rain slide off naturally

Front panel snaps in and can be pulled out easily for seasonal cleaning

Drainage holes on the base to keep the interior dry

Dimensions: 120 mm deep, 250 mm tall, 125 mm wide

Perfect for gardens, balconies, or wooded areas.
Mount it using screws, zip ties, or brackets — design allows for various mounting strategies.

Designed with 3D printing in mind (no supports needed if oriented properly).
Tested in PETG and ASA for durability outdoors.
