Printable Airframe Mk I

Although difficult to print, this is my first shot taken at a printable airframe. The frame is primarily made of carbon fiber rods (or aluminum tubes, but wood is not recommended) of a 4mm diameter (when at 100% scale.) The fuselage is very primitive for the time being. At this point, no motor mount or battery strap is present, and servos would be glued onto the wing surface and the fuselage hub.
The wings and tail are intended to be covered in cellophane or shrinkwrap, hence the ribs.

Please note: the tail pieces are at 75% scale relative to the other pieces.

Update: Motor mount added. Mesh didn't tesselate into a solid, so I also uploaded a .step file.
