I noticed that most 3d printed terrain is the same as traditionally modeled terrain and did not take advantage of the unique properties of 3d printing.
Ecaroth's Dungeon sticks make the body and Superbeasti's grass makes the spirit of this model.
Frankly i dont know what you would use this for in a DnD context but i think the technique is really cool.
The grass is modeled such that at .2mm layer height it should print a single line per thread.
Do not scale or the grass will not print.
Check the Layer view to make sure the grass is going to print.
Cut the top of the grass away from the opposite wall.
Fold the grass up on both male and female sides.
Attached both halves and glue together.
