Wishbone

My idea was to have spares for the thanksgiving dinner.
I thought I was original but apparently there have been others.
should print ok with **2 shells 0% infill**

make a few spares for the kiddies.
or make one for a bird in need of a transplant.
version **wishbone2a.stl** (third iteration)
has thinner section for easier breaking
and now properly adjusted to lay it flat.

I have added a version without the "cuts" that make it have a
break point as there was a request for the "uncut" version.
