I was looking at all the great ideas for flying things and in discussing them at work a friend mentioned the seeds from maple trees..
so I drew a similar shape based on them and added a hook for launching.
I printed this one with the iron filled PLA, but regular PLA would suffice.. I also enlarged it by 50% to get a 3" tip to tip width.
It's flexable and if you heat the wings slightly you can add airfoil shape.
The author marked this model as their own original creation.
