Kobold Barricade
Perfect for tabletop RPG encounters!
I did my best to remove the original file's spikes and just create a simple barricade. I couldn't remove them fully, but I was able to add a plank that allows you to stand minis up on it. The plank may take a few tries, and I would recommend using hot glue to attach it rather then Krazy Glue like I used. Just be sure to use your minis to mark what height you want it BEFORE gluing! I almost made that mistake myself.
It doesn't need any special settings, just use your defaults. Though I would recommend checking out this thing for some great accessories for it. http://www.thingiverse.com/thing:635741
It can be used with OpenForge, but I URGE YOU to make sure you have it scaled to your liking, because I print my tiles at 120% along the x & y to allow for 30mm minis. As a result, any time I convert something to be printed, I load in a few parts of terrain and scale them to size before scaling it to match. Meaning I don't put much emphasis on proper scaling prior to the conversion step.
