Stackable Hex Tray w/ optional lid

Update 6-26-19

Added a version of the short 7 hex box that has a ventilated bottom. Less material and you can see what is inside from below. More to come.

---------------------
Somewhat inspired by dantu's hex container (https://www.thingiverse.com/thing:3681335), but done from scratch in OpenSCAD.

Includes small (pictured), medium and tall versions, which will stack together. Also created a lid if you want one.

If you wanted to try them out without printing the whole thing, I also included a single version.

It would be relatively easy to make other versions of this with the code, so if you have some variation you'd like me to make just drop a comment.
