This is my dragonfly.
I designed it for the MakerWorld Flying Objects Design Contest.
Make sure to watch the short GIF in the modelpictures.
After print, just rotate the head and tail into place, push the wings into the inner joints, and put the model on the stand.
Enjoy!
Update:
I added the “Dragonfly loose joints” profile (red Dragonfly picture).
Use this profile, if your head and tail joints are too tight!
I designed it with more space between the joints.
Have fun!
