This piece serves at least two purposes. First it can resolve the gap that's formed when you create a corner with two wall pieces. Second, it can be used as a structural beam to help hold up additional levels.
Given the huge number of variations there could be to tile sizes and pillar placement, I've created the most common ones. If you want another size/placement, add a comment and I'll get it uploaded.

OpenForge is now a patron supported project. I use the resources that my patrons give me in order to get the resources to let me create more sophisticated tiles with a greater level of detail. Please, support me, and I’ll deliver an ongoing stream of awesome gaming terrain. You can find more about OpenForge and Masterwork Tools at our:
