Wing Flapping Mechanism

I’ve received a few requests for instructions for Kristal’s kinetic Bat sculpture, and though I don’t know if I’ll be able to make them for the full model, I have started to document some of its components. Here are instructions for the mechanism used to flap the wings. Hopefully some people can make use of these to achieve similar motion in their own models, or even just to get a better understanding of how it goes together.

I explain how the mechanism works in detail in the main video, which you can find in the original blog post.
