Blackbird Nesting Box

This is a nest box for blackbirds.Blackbirds like open nest boxes with mini "stairs" inside.I recommend printing with PETG and in black color. The location should be somewhere that protects the birds from strong sunlight and at a height of about 1-1.5 meters. You need to use support. I recommend tree-shaped support to reduce material use and to make it easier to remove the support. I would like to warn you though that removing the support from the nest box is not very easy and takes about 20 minutes.
