After finding a 2nd hand flapping butterfly in a store I wanted to try design my own. It has a different shape and different materials so I had to adjust the design to compensate for that but it ended up working out nicely.
(WIP) The first prototype
(WIP) The new prototype. It only flaps a little bit after each push due to the added body weight so I added a pull string.
I also had to drill new holes in the wings to help balance the whole thing so I had to change the final hole position in my file.
