Tunefast Harp with cone

This is a more elaborate (perhaps too much so) version of Makefast's TuneFast harp.

Key features of this remix:
* Reinforcement struts to help prevent bending under string tension
* Hollow body with resonant cone and F style sound holes
* Same hardware as original
* More ergonomic shape
* No supports required

Note that the resonant cone tends to sound "better" when covered with the palm of your hand when playing. At least IMHO :)
