Heroscape walls (updated)

I modified my Heroscape wall sections so that they can fit end-to-end and make long walls and square enclosures.

There are several sizes for both the "horizontal" and "vertical" directions. Some are made for the end to be inside another wall, and some are made for the end to be flush with the outer edge--it might take a little work or trial and error to figure out which walls are needed for your enclosure.
