Flapping hummingbird

Flapping hummingbirdOne of the coolest birds has to be the hummingbird, with it flapping it’s wings quickly back and forth, rather than up and down. I tried to recreate that mechanism with a single rotational input. The result is this model, it might look a bit complicated, but it’s super easy to assemble. Just turn “handle” on the back and it'll flap it's wings, direction doesnt matter. Importantly a 3mmx20-28mm screw is needed for this. (you can try and print a 2.9 mm rod, but I can’t guarantee it’ll work, but an STL for it is included.) Depending on the printer quality, you might want to go for the “tight” versions of things if the joints are too loose, since they have smaller tolerances.
