About this 3D model

So, the other thing was a dart. Very purposeful and straight downwards movement on that thing.This one flies well, but I'll see if I can work out the CAD files for it.It was quite literally derived from the Free falling design. I changed it by hand until it worked.I have no idea if something like this is even printable with no support, and even so - the support may be stronger than the fragile wing. I will give the tip a flat foot to stand on. Printing vertically may be the only way forward.
