https://www.youtube.com/watch?v=2vsFSrN2SaA My wife loves hummingbirds which is why I designed my first hummingbird automata "Hummingbird" (https://www.youmagine.com/designs/hummingbird) . So what could possibly be better than having a hummingbird automata? Why this dual hummingbird automata, "Hummingbirds", of course! Assembled with over one hundred 3D printed parts and three purchased parts, "Hummingbirds" is quite definitely a challenge to print and assemble. And 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 Cura 4.2, and printed in PLA on an Ultimaker 2+ Extended and an Ultimaker 3 Extended.
