This is a remix of https://social.thangs.com/m/64839 by pressprint. I really love the details of that model, but the wings are fixed and you need to use super glue to assemble the model. I used tinkercad and Microsoft 3D Builder to modify the models, added gears etc to make the wings foldable. When printed in 50%, it can fit in your palm. Update 16 May 2022: added two parts, split the top for different print orientation for FDM printers, should be able to improve the quality.
