Whirligig, Hummingbird

As I've previously mentioned, my wife loves hummingbirds. By happenstance, after completing my previous two whirligig models, a Youtube follower asked if I could convert my previous hummingbird electric motor driven model into a whirligig. So I created this model, "Whirligig, Hummingbird", for my wife (of course!).

The model design incorporates components from my previous hummingbird models and universal joints from my previous propeller boat models, but also required some new components that I had not previously designed such as a face gear. The model performs two wind driven motions; the first being that the model follows an arched motion fore and aft allowing the humming bird beak to enter and exit a "flower", and the second motion being that of the flapping humming bird wings during the arched motion. The worm gear drive provides sufficient torque to generated the fore and aft motion of the hummingbird, and for the face gear 4:1 gear ratio that provides four wing flaps per fore and aft motion.

I 3D printed this model in Tough PLA and while Tough PLA is somewhat weather resistant, I recommend occasional outdoor use in dry windy conditions.

As usual, I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to ask as I do make plenty of mistakes.

Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.12.1, and 3D printed in Tough PLA on Ultimaker S5s and an Ultimaker 3e.
