As there's surely a relation between the maker scene and the UAV scene, I thought that might be interesting.
Fenner Drives came out with pretty tough but flexible TEP filament for 3D-printing a couple of months ago. I can imagine a ton of applications for this stuff in UAVs, like anti-vibration mounts or protective shells for autopilots, cameras, etc...

I have done some printing with Ninjaflex and some of the other flexible plastics. Its a challenge in 1.75mm, but its doable. I wound up making a guide tube between the knurled feed shaft and the entrance of my hot end to keep it from buckling. You need to go slow also since it is flexible so it can compress and expand laterally if you push too fast, resulting in a bind in the cold part of the hot end.
some extruder designs work better than others for this.
cool, will this work in most commercially available printers?
