Mendel framevertex thin shelled

I've been testing a bit with thin shelled frame vertexes lately.
But most small ribs added alof of time for printing.
So there was no print time reduction, only in mass a bit.
For this version2, i made a pretty good compromise between weight/printtime/strength (I think)
At least for PLA that is, i just printed one at 2500mm/min (the green one in pictures).
And im amazed about the strenght.. i think it was only a little bit quicker then normal, but i did use more dense settings.

But the weight reduction is 40%...
And off course alot less warping :)
Btw, Im not finished yet, so v2 is not final.

PS: There is a large and small (sm) STL, because i had trouble with repsnapper v333 and the large STL. With small i mean less triangles/facets, not smaller dimensions
But maybe in other programs the large STL works fine also.
