This is a trick, an optical illusion: when the cage is rotated, the bird disappears and appears. The part is completely flat and printed with the same material.
I made two versions: one for a larger size (95 mm) and a smaller one.
I printed a large figure with a layer width of 0.5 and a nozzle of 0.8, but you can print with a smaller nozzle, the quality will be higher. The lines are thin, so good adhesion and alignment are important.
The author marked this model as their own original creation.
