Hello. I made a new feeder from scratch. suggesting the appearance of it https://www.thingiverse.com/thing:3705723 . but it has different dimensions and wall angle. dimensions 15cm x15cm x 17cm the bird can sit in front of the 5.3 cm hole I strengthened the attachment, with a string or thick wire. there are two versions. for one string or four strings, so that the house does not sway. The walls of the house are 2mm. you can reduce the printout to 80% size 12cm x 12cm
