Bottom triangles for yoyo hex display

I noticed when printing the yoyo Hex Display by tyeroc that after getting enough yoyos connected I got some flex when flat. I decided to slice their model to get a triangular section, and then print them (not in vase mode like the original). Once attached the entire display is much more rigid than before.

I rotated it to be flat on the long side, but you could print it vertically to match the other items. I didn't have any issues printing it flat.
