Robin Nesting Box (Robin Birdhouse)

I designed a nesting box for robins. I don't know if it works. It fits the A1 mini and it has nearly the size that is suggested for robins nesting boxes I found in the internet. You should print it with the back of the house on the printing bed. If you like the heart of the door in a different color, pause the print at the right height and change to the desired colour. The door snaps in easily with a little bit force. The holes are to let water run out and to have the possibility to attach it somewhere. If You want to attach it with the back somewhere, please make your own holes like You need it.
