Bird House Entrance
Description
I designed a extended entrance for a bird house. Crows managed to eat at the entrance to our old bird house and pull out the baby birds. This should make it harder for them to fit their heads in the entrance as well as strengthen the hole to make it harder to chew through. Designed with a 25mm hole which should accommodate most small birds. Requires 2x M3x10 mm self tapping countersunk screws. Optional (but recommended) 3mm round bar (wood, metal or plastic) Assembly: 1. With the two screws, attach the Bird House Entrance over the hole of the Bird house. 2. If you want to add the round bar, cut it to 28mm long and push it through the holes in the side. This should only need to be held in place with friction but if the bar moves you can add a bit of glue.
