Modular hex plant support

Didn't like the fit of the ones on here so designed my own. Each hex has a finger/hole on each of the 6 sides to make a better joint, and the dogbones provide a nice lock. Everything should print without supports.

* Update: I added a rev 02 that has snap joints that seem to lock in much better. They aren't as removeable, but that's sort of the point. Just plan ahead and snap everything together.
