About this 3D model
I designed a tiny bird to be printed in a line art style. I added a file with just the round frame and the bird, but also a file with an additional hole to be mounted on the wall. I found a free image of a bird online and edited it in a program, where I added the frame, leafs and also some connecting lines, so everything can pe printed as one. I recommend using a brim to make sure the frame hold on to the build plate. Of course the files can be scaled up or down, but they should not be too small.
